UK Part 145 caters for certain maintenance tasks to be carried out at an unsupported location by the aircraft commander or flight engineer.

AMC to Part 145.A.30(j)4 lists various minor maintenance tasks or simple checks which the aircraft commander or flight engineer may be issued an Authorisation to carry out.

Other checks or replacements involving simple techniques which are not listed in AMC 145.A.30(j)(4) paragraph 2(i) require specific agreement from the Civil Aviation Authority (CAA). If you would like a simple maintenance task or check to be considered for the issue of an authorisation under AMC 145.A.30(j)4, please apply to the CAA by following the information detailed in this page.

How do I apply?
