Aircraft Cleaning is considered PM-Preventive Maintenance as listed in the
A&P handbook Ch. 6-19 thru 6-25.
You will also find the aircraft cleaning procedures listed in the aircrafts Maintenance Manual making it an A&P ticket item only but nobody bothers to look there especially the FAA (they don't even know how!).
The FAR's describe PM as work that can only be accomplished by an A&P or by the Pilot/Owner of their own aircraft if Part 91. Part 135 and 121 only by an A&P.
If the work is performed by the Pilot/Owner they have to do their own work. If by an A&P, the A&P can supervise and sign the logbook.
The FAA in the last 5 years has turned their backs on the A&P mechanics and are allowing auto-detailers to come onto the airfields and clean aircraft. This has saturated the market and brought prices way down. Good for the aircraft owner (pocket book not safety - does Aeroperu 603 come to mind!) not so for the A&P.
If you're an A&P reading this and thinking that cleaning aircraft isn't what you signed up for consider this:
Turning wrenches you're making $35/hourly to $45 if you're lucky.
Cleaning aircraft, $120/hourly
Got your attention yet!?
It's time to put a stop to auto-detailers taking over the aviators jobs. To make this happen go to your local FAA and make a formal complaint.
Chances are (better than 95%) your local FAA will not give you the time of day with this. Insist that they give you a real answer. They will then get back to you and pawn you off to another agency within the FAA which will then put you in an endless loop.
Like most Gov. workers they are lazy and too afraid to take responsibility and initiative.
When this happens write a formal complaint using the FAA online forms found at
http://faa.custhelp.com/app/ask. They FAA will then have to investigate and respond back to you.
Go get 'em!... And start making some money!
