Aircraft maintenance checks are periodic inspections performed by technicians on every commercial or civil aircraft after a defined period of time or usage. 4. Each operator prepares a Continuous Airworthiness Maintenance Program (… It needs about 120-150 man-hours, depending on the aircraft, and is usually completed within 1–3 days at an airport hangar. This shortens the time the aircraft is out of service, by performing two distinct tasks simultaneously. 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. Airlines and other commercial operators of large, or turbine-powered, aircraft follow a continuous inspection program approved by the Federal Aviation Administration (FAA) in the United States,[1] or by other airworthiness authorities such as the Transport Canada Civil Aviation Directorate (TCCA), or the European Aviation Safety Agency (EASA). D CHECK The actual occurrence of this check varies by aircraft type, the flight cycle count, or the number of hours flown since the last check. (b) The approved procedures must include each item necessary for flight crewmembers to check for safety before starting engines, taking off, or landing, and in engine and system emergencies.

Maintenance Review Board (US) The A check is performed approximately every 400-600 flight hours, or every 200–300 flights, depending on aircraft type. Aircraft maintenance checks are periodic inspections performed by technicians on every commercial or civil aircraft after a defined period of time or usage. This check occurs approximately every 6-10 years. The A check takes a minimum of 10 man-hours. As an added safety measure, jacks should be inspected before use to determine the specific lifting capacity, proper functioning of safety locks, condition of pins, and general serviceability.

Both checks are done for flight instruction or for-hire crafts, although 14 CFR Part 91 only calls for the 100-hour examination. The maintenance includes scheduling the repair of known problems; replacing items after a certain air time, number of cycles or calendar time; … The aircraft must not leave the maintenance site until it is completed. (military aircraft normally follow specific maintenance programmes which may or may not be similar to those of commercial/civil operators). Night Operations 8.1 General 8.2 Night Solo Operations Rev. This may include new seats, entertainment systems, carpeting, etc. The B744 Phased "A" check (PA-1, to PA-4) is a grouping of "A" up to "4A" check tasks distributed evenly to be done at every 1000 FH/220FC/60 Days whichever is earlier. This allows for more flexibility in the scheduling of maintenance to minimize aircraft downtime. PHASED “A” CHECK (B744 Passenger Aircraft) as an example. Turn on the master power switch. The air carrier must have procedures in place to ensure an aircraft, which does not meet its TC, is in safe condition for the … Caution: •Normally, rigging and alignment check should always be performed inside the hangar. 25.1529 of 14 CFR part 25. It is also known as an IL or “heavy maintenance visit” (HMV). The effort needed to complete a C check is up to 6,000 man-hours. Ailerons into the wind and elevator about ½â€ back from the gust lock hole. [12] On average, a commercial aircraft undergoes two, or three, D checks before being retired. The requirements and the tremendous effort involved in this maintenance check make it by far the most expensive, with total costs for a single visit ending up well within the million-dollar range. Maintenance intervals based on usage parameters allow more flexibility in scheduling the maintenance program to optimize aircraft utilization and minimize aircraft downtime. A good example of a functional check flight procedure required outside the aircraft manufacturer's control is the Challenger 604 Air Driven Generator (ADG) test. 2. Depending on the parking/storage duration, some specific maintenance procedures and repetitive ground checks will apply. •If this cannot be avoided – the a/c should be positioned with the nose into the wind. Apply smooth full power, then check for at least 2300 RPMs and oil temperature and pressure in the green. If the fuel is low, call for the service truck to bring your fuel out while you continue to do the rest of your checks.

Before beginning a study of aircraft weighing procedure or attempting the actual weighing of an aircraft, it is necessary to become familiar with the weight and balance information in the applicable Aircraft Specification or Type Certificate Data Sheet. Notwithstanding the importance of thoroughly checking the aircraft prior to each flight, it is all too common to see pilots walking round 'going through the motions' but seeing nothing. Prior to beginning any aircraft operations, it is necessary to undertake a pre-flight check of the aircraft. AIRCRAFT WEIGHING PROCEDURE.
