Do Helicopters Need A Lot of Maintenance?
Although a few parts of the helicopter may be approved to be used until worn to acceptable limits (“on-condition”), the majority must be changed when a time or cycle limit is reached. For example, a part may require inspection each 300 flight hours, overhaul at 2,400 hours and retirement at 4,800 hours. A part that has reached the mandatory retirement time or number of cycles must be destroyed even though it may appear to be in good condition. As in all aircraft, the pilot is required to do a “pre- flight” inspection to insure that the helicopter is ready for flight. A “daily” inspection, usually conducted by an JAA certificated mechanic, may also be required. In addition, the JAA may require additional inspections, such as an annual inspection, a 100-hour inspection, or “continuing” (periodic) inspections according to an approved JAA program.
