The last macro activity (aircraft delivery) consists of the customer receiving procedure, a compliance check list application and the maintenance flight, which ensures that all systems are functioning properly. As part These procedures help determine the airworthiness of an aircraft and ensure the safety of its next flight and the crew and passengers it is carrying. In fact we could just roll along with a check mark in each row as we accomplish work on the aircraft. This shortens the time the aircraft is out of service, by performing two distinct tasks simultaneously. [12] On average, a commercial aircraft undergoes two, or three, D checks before being retired. Such a check can generally take up to 50,000 man-hours, and 2 months to complete depending on the number of technicians involved. Pre / Post Flight Operations 7.1 General 7.2 Pilot’s “I’M SAFE” Check List 7.3 Equipment 7.4 Aircraft Preflight 7.5 Pre / Post Flight Briefings 8. 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.

It also requires more space than A and B checks, therefore, it is usually carried out in a hangar at a maintenance base. In the United States, initial aircraft maintenance requirements are proposed in a Maintenance Review Board (MRB) report[5] report based on Air Transport Association (ATA) publication MSG-3 (Maintenance Steering Group – 3rd Task Force). 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.
