Part 91 Minimum Equipment List (MEL)

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.

What an MEL is

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.

Which MEL do you need?

Part 91 operators have two LOA options. Which one fits depends mainly on where you fly.

LOA D095

MMEL as your MEL

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.

LOA D195

Aircraft-specific MEL

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.

What a good MEL includes

Current MMEL

Built from the latest MMEL revision for your type, and kept current as it changes.

Your actual aircraft

Number installed and required for each item, including STC and aftermarket equipment.

(O) and (M) procedures

The operations and maintenance steps required before deferring an item.

Deferral control

Categories, time limits, placarding, and tracking so nothing gets missed.

What we need from you

  • Aircraft make, model, serial number, and registration
  • Equipment list, including STCs and aftermarket installations
  • Where you fly (domestic or international)
  • Your current MEL or MEL procedures, if any

What we deliver

  • MEL built from the current MMEL and your aircraft configuration
  • (M) and (O) procedures for each applicable item
  • D095 or D195 LOA application and FSDO coordination
  • Optional electronic MEL and deferral tracking through myFLIGHTDATA
  • Revision service as the MMEL changes
  • PDF and secure online copies for your EFB

Where applications get stuck

These are the issues we fix most often on MELs we review.

Out-of-date MMEL

An MEL built on an old MMEL revision is not current. Updates must be tracked.

Missing STC equipment

Aftermarket and STC equipment must be in the MEL, or it cannot be deferred.

No (O) and (M) procedures

Items marked (O) or (M) need written procedures before they can be used.

Previous owner’s MEL

LOAs belong to the operator. A new owner needs a new authorization.

Domestic MEL abroad

An MMEL-as-MEL may not satisfy foreign ramp inspectors. D195 is the safer choice for international trips.

No deferral tracking

Deferred items need time limits, placards, and a record.

MEL questions

Which is better, D095 or D195?

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.

How often does an MEL need updating?

Whenever the MMEL is revised or the aircraft configuration changes. We track MMEL revisions for our clients.

Can you handle Part 135 MELs too?

Yes. See our MEL / e-MEL page for Part 135 and other operators.
