The replacement of parts is often noted in an aircraft lease agreement, as such the lease agreement will stipulate what can and what can not be used, on occasion it will also refer to a location and or part of the aircraft also.

The expense would be addressed by the lessee and statement such as “Lessee, at its own cost and expense, shall promptly replace, or procure the replacement of all Parts which may from time to time become worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for their intended use for any reason whatsoever”.

While it is now commonplace to have a safety management system (SMS) in place they are reliant on some additional considerations such as people using them and reports being made.

For this purpose, we need to promote and encourage a reporting culture –it can even sound negative that we need to report, but the reality is that reporting is not negative, it is a positive demonstration of a culture that accepts it will make mistakes and is interested in how to reflect and rectify them.

A bare metal inspection is commonly abbreviated to BMI and is commonly used to refer to the inspection of a metallic fuselage that is stripped of paint.

It is not a mandatory task to repaint aircraft, the paint is a protective layer and while it must be maintained, it can be repaired or “touched up” as required. With this in mind then we can determine that the fuselage is not in this condition regularly.

For some end-of-lease requirements, part of this is to present the aircraft in a white livery. It might not always require a repaint of everything and might be limited only to the fuselage or only covering logo for example.

The value of the reliability data is important to the airline operating the aircraft not only to demonstrate compliance as a reliability programme is required by regulation but also to amend the Aircraft Maintenance Program for the operators’ aircraft (such as extending or reducing interval threshold) based on their experience and operating environment.

The aircraft paint input is a complex event often carried out on a tight timescale and with budgetary considerations. The induction into paint is an important time and you should be aware at this time of the contacted options on the paint input.

Often the contract might state costings based on paint thickness on different areas –it is important to check the paint thickness measures in microns and ensure that samples are taken in multiple places onsurfaces.

A good practice is also to take many photos of the condition of the aircraft at this stage and note any damage, window condition, and ensure you have good quality images to refer to.The aircraft has multiple probes, ports, openings and antenna for example where it can be harder to prepare the aircraft for paint. Here masking and protection is a part of the process carried out before sanding and stripping begins.
