Boeing and Airbus maintenance planning data is written for airline operation, where an aircraft can fly 3,000 hours or more a year. When the same aircraft moves into private, corporate or government service and flies less than about 1,200 flight hours a year, that program no longer fits. Tasks driven by flight hours or cycles may not come due for years, while corrosion, seal ageing and the effects of standing keep advancing with time. A low-utilization program adapts the manufacturer’s program to how the aircraft actually flies.
Aircraft
Boeing Business Jets and other 737s, Boeing 747, 757, 767, 777 and 787, Airbus ACJ318, ACJ319 and ACJ320, and Airbus A330, A340 and A350, in VIP, corporate, government and special-mission service. AeroManuals has built programs for more than 60 Boeing Business Jets and more than 40 Airbus A318 to A320 aircraft, and for 737s operated by U.S. federal agencies and foreign air forces.
What the program includes
- Applicability review of every MPD task against the airframe’s configuration, STCs, ADs and service bulletins
- Calendar limits added to usage-only tasks, with tasks regrouped into check packages that suit the aircraft’s annual hours and cycles
- Airworthiness Limitations and CMRs carried forward exactly as the manufacturer publishes them
- A bridge from the airline program the aircraft was maintained to, with next-due dates recomputed from the compliance records
- A controlled program document ready for authority submission
Under every operating rule
Low-utilization programs are prepared for aircraft operated under Part 91 (including programs developed under 14 CFR 91.409(f)(4)), Part 125 and Part 135, for EASA-registered aircraft under Part-M, and for aircraft on other registers, including Bermuda, the Cayman Islands, the Isle of Man, Malta and Aruba.
Frequently asked questions
When does an aircraft need a low-utilization program?
When an aircraft designed for airline operation, such as a Boeing or Airbus airliner, is operated in a private or corporate environment and flies less than about 1,200 flight hours a year. At that level the airline program’s usage-based intervals no longer reflect how the aircraft ages.
Can I keep the standard MPD intervals and simply fly less?
You can, but usage-only tasks may then go years without being performed. That is why low-utilization programs add calendar limits to those tasks. Whether a given program is accepted depends on your operating rule and registering authority.
Does a low-utilization program change the Airworthiness Limitations?
No. Airworthiness Limitations and CMRs remain as the manufacturer publishes them. The program regroups MPD tasks and adds calendar limits; it does not alter the limitations.
What do you need to start?
The current maintenance program, a status report from your tracking system, the aircraft’s configuration and STC list, and the flight hours and cycles you expect to fly each year.
