Minimum Equipment List
Part 125 Minimum Equipment List issues can sometimes be troubling, depending on the FAA offices used and the combined experiences of the operator and the inspectors. We have developed complete MELs, including electronic versions such as found in Boeing Laptop Tools (BLT), for most of the larger aircraft. Our MEL library of completed versions is slightly over 110 aircraft types, from the B747 on down to single-engine airplanes and helicopters. We have not done a complete Boeing 777 nor 787 at this time.
This has included the Boeing fleets, of course, the BACs, and DC-6/9/10s, MDs and similar aircraft. Maybe an older Convair in there also.
For most Part 125-typeÂ aircraft we have past use, or factory guided (M) and (O) procedures and for the larger aircraft, usually using the Dispatch Deviation Procedures Guide (DDPG) and the Configuration Deviation List (CDL).
Part 125 Minimum Equipment List – Getting Started
However, having said that we need the operator’s input on what (M) and (O) procedures are workable for you. The (O)’s are usually not an issue, but the (M) procedures can be, so expect that you will have to work with our people to complete this.
To start an MEL we send you a worksheet that has information about installed STCs and a list from the MMEL that has the optional and variable items so you can indicate as to how many of those items you have installed. BUT, we need to have a discussion with you first to be sure we have a mutual understanding of any of the issues.
On the large aircraft we will likely need several weeks to first update our master files to the most current MMEL and then start to determine your equipment and issues with any of the procedures.
