2.0 MAINTENANCE PROGRAM PERSPECTIVE 2.1 Maintenance Program History -In the early days of aviation maintenance programs were developed primarily by pilots and mechanics.If you work for or operate an FBO or flight school that offers aircraft rental as well as flight instruction, whether Part 61 or 141, you know the timing for completing aircraft inspections can sometimes be confusing. Purpose of Inspection Programs Altimeter And Static System Inspection Required for every aircraft that is operated under Instrument Flight Rules (IFR).When is the 100-Hour Inspection Due for Aircraft Used for Rental and Flight Instruction?that the owner or operator establish an airworthiness maintenance and inspection program to be carried out by certified individuals qualified to issue an airworthiness certificate. Instead of completing the entire inspection at 300 hours, the tasks are divided into six inspections that are completed consecutively at. For example, an aircraft requires a maintenance inspection is completed every 300 hours. In a progressive inspection program (PIP), aircraft maintenance is divided into phases and occurs at fixed intervals.Provider of cost-effective aircraft and jet engine maintenance services. 91.409(b) and its timing and limitations that are sometimes misunderstood. Rather, it is the 100-hour inspection under 14 C.F.R. That requirement isn't particularly confusing.
If the flight is operated for the purposes of providing flight instruction, then the aircraft must have had an annual or 100-hour inspection within the preceding 100 hours of time in service. And this is where some of the confusion occurs. However, if that happens, the additional time used to fly to the facility performing the inspection must be included in computing the next 100 hours of time for the aircraft to be in service.Now, in order to determine whether the 100-hour inspection is required for an aircraft that is used for both flight instruction and rental, and when that inspection is due, we need to look at how the aircraft is operated during a particular flight. Part 125 is not applicable), turbojet multiengine aircraft, turbopropeller-powered multiengine aircraft, or turbine-powered rotorcraft which has selected an inspection program under Section 91.409(f), then that aircraft must receive an annual or 100-hour inspection if it is going to be used for flight instruction.Keep in mind that the 100-hour limitation may be exceeded by up to 10 hours as long as that time accrues while the aircraft is enroute to reach a place where the inspection can be done. Msr605x driversThe 10-hour grace period does not apply because the aircraft was not being flown enroute to a location where the inspection will be performed. A 100-hour inspection of the aircraft is performed when the aircraft returns from the flight.Is this a violation of Section 91.409(b)? Yes, because the flight instructor and student pilot clearly intend to fly beyond the 100-hour limitation during their training flight. At the time of dispatch, the aircraft has accumulated 99.9 hours of time in service since the aircraft's last inspection. In fact, when the customer returns the aircraft does not need an annual or 100-hour inspection unless it is going to be used for flight instruction, or 12 calendar months have elapsed since the aircraft's last annual inspection.Example 2: The FBO or flight school dispatches an aircraft on a local training flight with a flight instructor and student pilot that is anticipated to, and does last one hour. If the customer's flight does not exceed 10 hours and a 100-hour inspection is performed upon the aircraft's return, does this violate Section 91.409(b)? No, because the aircraft is not being operated for hire or to provide flight instruction. When the customer reserves the aircraft, it has a total of 95 hours of time in service since the aircraft's last annual inspection. ![]() The original departure airport). Additionally, the 100-hour limitation was exceeded while the aircraft was enroute to a location where the required inspection will be performed (e.g. Why? The flight instructor and student pilot did not intend to overfly the 100-hour limitation. Upon return, a 100-hour inspection of the aircraft is conducted.This situation does not violate Section 91.409(b). Aircraft Inspection Program Free To RentHowever, before the aircraft is again used for flight instruction an annual or 100-hour inspection must be performed and the next inspection after that must be performed before the next 85 hours of time in service in order to continue to use the aircraft for flight instruction.As you can see, in order to apply Section 91.409(b)'s 100-hour inspection limitation it is important to not only look at the purpose of a flight, but also the intention of the operator in conducting the flight. The 100-hour inspection requirement does not apply to aircraft operated for rental purposes and the FBO or flight school is free to rent the aircraft to customers as long as it is not providing a flight instructor or pilot and the customer is not operating the aircraft for hire. Additionally, no flight instruction is performed with the aircraft during the week.Similar to Example 1, this situation does not violate Section 91.409(b). As a result, the aircraft's schedule is marked "for rental use only." During the next week the aircraft is rented to customers, without a flight instructor, who accumulate a total of 15 hours of flight time. Although the aircraft is used for flight instruction, an inspection cannot be performed within the next week. With an understanding of Section 91.409(b)'s limitations and documentation in hand, you will be able to prove that you properly performed your 100-hour inspections in compliance with the regulations. Local, cross country etc.). Rental or flight instruction) as well as the intentions for the flight (e.g. Aircraft schedules and rental agreements should include the purpose of the flight (e.g.
