It takes about 160-180 labor hours, depending on the aircraft, and can be completed within 1–3 days at an airport hangar. Maintenance costs will also vary according to aircraft type, i.e., a light jet vs. a medium vs. a long range. : Checks A-1 through A-10 complete all the B check items. This type of check often requires an aircraft to stay at a maintenance facility for the necessary space/tools/maintenance technician working hours/materials. The process can take upwards of 30,000 to 50,000 labor hours over a period of four to six weeks. Sometimes, this maintenance is done overnight as to not interrupt the schedule that airlines keep. This check puts the aircraft out of service and until it is completed, the aircraft must not leave the maintenance site. For example, a schedule might have aviation maintenance technicians performing C1 check tasks on a certain day and then the next day continuing with C2 and so on. The maintenance work during A checks often covers general inspections of the interior and the aircraft hull for evidence of damage, deformation, corrosion, missing parts. (military aircraft normally follow specific maintenance programmes which may or may not be similar to those of commercial/civil operators). We managed the logistics and streamlined the entire process. For airlines and operators to efficiently maintain, repair, and overhaul an aircraft, some B check tasks have been absorbed into A check phases. Pilots … It is also known as an IL or “heavy maintenance visit” (HMV). They ensure and certify that the aircraft is fit to fly. Most aircraft would receive about 12 hours of line maintenance per week. It currently has no operational aircraft to fly. Like the A Check, the B Check is mostly routine maintenance but expanded to include a more thorough inspection and maintenance of some engine components, aircraft part replacements, and more. It is, therefore, usually carried out in a hangar at a maintenance base. This is performed approximately every 400-600 flight hours or 200–300 cycles. This type of maintenance generally includes 100-hour inspections, annual inspections, and progressive inspections as well as preflight checks to ensure the aircraft is airworthy and ready to be flown. It is, therefore, usually carried out in a hangar at a maintenance base. Such a check can generally take up to 50,000 man-hours and 2 months to complete, depending on the aircraft and the number of technicians involved. Line checks require minimal tools and are usually done at the airport gate under the “open sky.”. This helps by reducing aircraft downtime, reducing time maintenance technicians work on the aircraft, improving maintenance scheduling, and implementing better usage of resources such as hangars and test equipment. Because of the nature and the cost of such a check, most airlines — especially those with a large fleet — have to plan D checks for their aircraft years in advance. The A check is performed approximately every 400-600 flight hours, or every 200–300 flights, depending on aircraft type. Each airline/operator is different, as is each aircraft. Modern transport category airplanes with MSG-3-derived maintenance programs employ usage parameters for each maintenance requirement such as flight hours, calendar time, or flight cycles. This is by far the most comprehensive and demanding check for an airplane. Sometimes, this maintenance is done overnight as to not interrupt the schedule that airlines keep. Predictive Maintenance: How necessary are aircraft checks? Eurocontrol [] described that even though current maintenance programs are planned according to the Maintenance Steering Group (MSG) 3-task oriented principle, the letter check classification is still preferred in the aviation industry.However, in practice, it stated that depending on MRO organizations and aircraft types, the mandatory tasks and labor numbers will vary. Every pilot is … To preserve the life of the aircraft and maintain a record of safe performance. We also repaired 25 that were pulled of the aircraft at the MRO. This would typically include Pre-flight checks, Daily checks (before first flight) Fluids, Failure rectification as well as Minor, scheduled maintenance tasks as follows. Aircraft maintenance is the performance of tasks required to ensure the continuing airworthiness of an aircraft or aircraft part, including overhaul, inspection, replacement, defect rectification, and the embodiment of modifications, compliance with airworthiness directives and repair. All aircraft are different and may require maintenance checks at different times than others. This is performed approximately every 20–24 months or a specific amount of actual flight hours (FH) or as defined by the manufacturer. Given the time requirements of this check, many airlines use the opportunity in order to also make major cabin modifications on the aircraft, which would otherwise require an amount of time that would have to put the aircraft out of service without the need for an inspection. In the United States, aircraft maintenance programs are overseen by the Federal Aviation Administration (FAA). All above check and maintenance involve man-hour charges. Inspecting things like wheels, brakes and fluid levels (oil, hydraulics) are done during transit checks. The C check requires an aviation maintenance technician to perform a deep inspection of a majority of the aircraft’s parts. With the entire aircraft stripped down and equipment removed, airlines often decide to refurbish aircrafts’ interiors and upgrade them altogether during D checks. Aircraft maintenance checks are periodic inspections that have to be done on all commercial and civil aircraft after a certain amount of time or usage; military aircraft normally follow specific maintenance programmes which may or may not be similar to those of commercial and civil operators. On average, a commercial aircraft undergoes three D checks before being retired. This type of maintenance is the most routine. This is performed approximately every month. Whether you are a flag carrier, a lessor or a low-cost airline, whether you operate an Airbus, a Boeing or a regional aircraft fleet – we are your single source for all aspects of maintaining your aircraft. Established in 2015 and building on more than 60 years of engineering excellence, 2Excel Engineering is a Maintenance and Repair Organisation (MRO) based in Hampshire, delivering service-orientated narrow body Boeing and Airbus Maintenance to Operators and Owners, Leasing Companies … Lasham, Hampshire. Line checks happen the most frequently, as they cover basic inspection checks. The CAMP outlines routine and detailed inspections or “checks” of aircraft they have in their fleet. It also requires the most space of all maintenance checks, and as such must be performed at a suitable maintenance base. While the FAA oversees the regulations and programs, it is up to the actual airline or operator to ensure that maintenance gets done and up to CAMP specifications. Aircraft need line maintenance every 24 to 60 hours of accumulated flight time, but it depends on the operator of the aircraft! Airlines casually refer to these checks as one of the following: A check, B check, C check, or D check. This maintenance check is much more extensive than the B check, requiring a large majority of the aircraft's components to be inspected. Also, the C maintenance check can often take the aircraft out of service for 1–2 weeks. Aircraft maintenance checks are periodic checks that have to be done on all aircraft after a certain amount of time or usage. Walk around inspection by flight crew is not normally a part of a maintenance program. It’s time to dream bigger. The entire package of rotables, consumables, and expendables, were at the MRO on time and on budget. D CHECK There comes a certain point where airlines realize that the cost of repair is more than the actual cost of the aircraft. Aviation maintenance professionals perform B maintenance checks approximately every 6-8 months. This type of maintenance is useful for large fleets because aircraft can be strategically serviced at times that are more convenient for the owner of the fleet. Aircraft maintenance checks refer to the periodic inspections every commercial and civil aircraft must go through after completing a specific number of flying hours or length of time of use. Please check if any of these measures apply to you. (takeoff and landing is considered an aircraft “cycle”), depending on aircraft type. It also requires more space than A and B checks, therefore, it is usually carried out in a hangar at a maintenance base. Under FAA oversight, each operator prepares a Continuous Airworthiness Maintenance Program (CAMP) under its Operations Specifications or “OpSpecs”.The CAMP includes both routine and detailed inspections. Checks, short for maintenance checks, are conducted at intervals specified by the aircraft manufacturer and approved by the regulator of the country where the airplane model is primarily designed and/or manufactured. A ‘bridging check’ is not in itself a maintenance package; rather it is the result of a detailed analysis of the pre and post transfer tasks to identify any differences which need to be addressed during the transfer bridging check. Prepared by System Safety, Atlantic Region. Aircraft maintenance checks are periodic inspections that have to be done on all commercial/civil aircraft after a certain amount of time or usage; military aircraft normally follow specific maintenance programmes which may or may not be similar to those of commercial/civil operators. Fill out the form below to get started! It also requires more space than A and B checks. In this scenario, an aircraft maintenance crew works as the backbone of air travel. The following are reminders for aircraft maintenance engineers (AME) prior to performing aircraft operational or functional checks. Often, older aircraft being phased out of a particular airline’s fleet are either stored or scrapped upon reaching their next D check, due to the high costs involved in comparison to the aircraft’s value. Aircraft Maintenance Check Manager. Fixing a component before it breaks down saves time and money. This usually happens after two or three D checks. B Checks that were common for older aircraft such as the B737-300, -400, -500, L1011, and MD80 have mostly been incorporated into Checks A1 through A10 (or A12). An Aircraft Maintenance Technician refers to an individual who holds a certificate issued by the Federal Aviation Administration; the rules for certification, and for certificate-holders, are detailed in Subpart D of Part 65 of the Federal Aviation Regulations (FARs), which are part of Title 14 of the Code of Federal Regulations. Commonly, aviation maintenance technicians will inspect things like wheels, brakes, and fluid levels (oil, hydraulics) during line checks. The aviation industry is highly regulated, meaning that airlines and other commercial airline companies must practice continuous inspection programs established by aviation authorities. Recently Argentinian carrier Flybondi sent its last Boeing 737 to a C Check in Mexico. Aircraft maintenance checks are periodic checks that have to be done on all aircraft after a certain amount of time or usage. C and D checks typically fall under “heavy maintenance,” and are much more extensive than the B check. This is a general overview of the types of work aviation maintenance technicians can expect on a day-to-day basis! Line maitenance, base maintenance and workshop. Defect rectification 3. Maintenance intervals based on usage parameters allow more flexibility in scheduling the maintenance program to optimize aircraft utilization and minimize aircraft downtime. The Federal Aviation Administration sets this system in place, and it is up to airlines and other aviation operators to implement the system and ensure it is being followed. Preflight Checks . This maintenance check is much more extensive than a B check, requiring a large majority of the aircraft’s components to be inspected. The objective of these checks is to conduct both routine and non-routine maintenance of the aircraft. The schedule of occurrence has many factors and components as has been described, and thus varies by aircraft category and type. Scheduled checks include annual, pre-flight, 50-hour and 100-hour and progressive inspections, which all fall under preventative maintenance. A progressive maintenance routine allows aircraft to undergo FAA and manufacturer inspections continually, as opposed to one all-encompassing check. Scheduled aircraft maintenance is preventative maintenance that is performed at regular intervals. Other work performed could entail things such as: Next, B checks are often completed during the A check phase, as airlines and operators have phased out B checks. The A check is performed approximately every 400-600 flight hours, or every 200–300 flights, depending on aircraft type. It is a check that more or less takes the entire airplane apart for inspection and overhaul. These are generally performed every 12-18 months, depending on the type of aircraft and the manufacturer’s specifications. B-checks are more extensive than A checks, but can also be completed overnight. Sometimes called post-flight, maintenance pre-flight, service check, and overnight checks, this is the most typical maintenance service performed on aircraft. The time needed to complete such a check is generally 1–2 weeks and the effort involved can require up to 6,000 man-hours. A similar occurrence schedule applies to the B check as to the A check. Lara Moro Mar 15, 2019 5492 Views 0 Comments. These do not, and are not meant to, replace a TC/FAA-approved aircraft flight manual, or the aircraft’s pilot operating handbook (POH) operation checklist. Additionally, it is important to view this list as a general and brief overview of the type of maintenance checks performed by technicians. Aircraft have set checks at various intervals, often known as flight line maintenance checks and also four different types of higher-level maintenance: A, B, C, and the heaviest (D) checks. This section does not cite any sources. Aircraft maintenance checks involve a series of activities, such as inspection, overhaul, reformation, defect rectification, and repair that help ensure air transportation is as safe as possible. D checks are comprehensive inspections and repairs of the entire aircraft and can mean taking apart the aircraft to inspect for damage and corrosion. This is performed approximately every 6-8 months. A and B checks are lighter checks, while C and D are considered heavier checks. You may experience longer than usual wait times or partial service interruptions. Above all, preventing damage to aircraft and working to keep that aircraft flying safely is what it’s all about to be an aviation maintenance technician! The FAA requires each airline/operator to establish a Continuous Airworthiness Maintenance Program (CAMP).
