Fly legally with inoperative equipment. We build your MEL from the current MMEL and your actual aircraft, with the operations and maintenance procedures behind each item.
A Minimum Equipment List tells you which equipment can be inoperative while the aircraft is still legal to fly, and under what conditions. It is built from the manufacturer’s Master MEL (MMEL), approved by the FAA for your aircraft type.
Without an MEL, most turbine aircraft cannot fly with any required equipment inoperative. With one, you defer the item, follow the listed procedures, and keep the trip.
Part 91 operators have two LOA options. Which one fits depends mainly on where you fly.
The common choice for noncommercial Part 91 operators. You use the current MMEL as your MEL, together with the Part 91 MMEL preamble and an operator procedures document covering the (O) and (M) items.
An MEL written for your specific aircraft, including STC and aftermarket equipment. Recommended for international trips, where foreign ramp inspectors expect an aircraft-specific MEL. D195 is also eligible for the FAA’s streamlined Part 91 process.
Some aircraft, such as non-turbine airplanes, may operate with inoperative equipment under §91.213(d) without an MEL. Turbine aircraft generally need an MEL.
Built from the latest MMEL revision for your type, and kept current as it changes.
Number installed and required for each item, including STC and aftermarket equipment.
The operations and maintenance steps required before deferring an item.
Categories, time limits, placarding, and tracking so nothing gets missed.
These are the issues we fix most often on MELs we review.
An MEL built on an old MMEL revision is not current. Updates must be tracked.
Aftermarket and STC equipment must be in the MEL, or it cannot be deferred.
Items marked (O) or (M) need written procedures before they can be used.
LOAs belong to the operator. A new owner needs a new authorization.
An MMEL-as-MEL may not satisfy foreign ramp inspectors. D195 is the safer choice for international trips.
Deferred items need time limits, placards, and a record.
D095 is simpler and suits most domestic Part 91 flying. D195 takes more work up front but gives you an aircraft-specific MEL that holds up better on international ramp checks.
Whenever the MMEL is revised or the aircraft configuration changes. We track MMEL revisions for our clients.
