 Posted: Wed Aug 18, 2010 7:43 am Post subject: Yak 52 Control Surface Covering and Balance References |
 |
|
I am currently working off a punch list from an inspection by the local FAA FSDO Airworthiness Safety Inspector following a 18 month repair of damage from Hurricane Ike. The control surfaces were all replaced with new or serviceable units provided by and recovered by a FAA-certified shop. I did the control surface installations, which were inspected by a local AP (who did the airframe sign-off) and an AI (who performed the Condition Inspection). The Inspector asked for a Yakovlev Yak 52 factory document citation that defines how the control surfaces must be re-balanced prior to a recover or not. Here are his exact words –
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
“Review the maintenance manual concerning control surface balance, if none is required or it has been accomplished, provide a reference”.
He also asked if there were a citation in the factory manuals regarding the process and materials for control surface recovering. I pointed out that the aircraft was covered using the Poly-Fiber system. He then requested a list of aircraft approved for recovering by Poly-Fiber, which should include the Yak 52. I thought that the covering system manufactures only listed Standard Category aircraft and not Experimental Exhibition.
Can anyone help me through this?
Thanks,
Steve

YAK-52 is expermental. I think this is crazy. I have run into this balance of control surface issue in other experimental aircraft. There is no chapter or book dealing with the specifics. I would say balanced using standard accepted methods. just my thought

I can help you.
Go to the EAA's web page. Call the number listed dealing with FAA issues. They will walk you through the exact process of how to tell your FAA Safety Inspector that he is exceeding his authority and is misinterpreting requirements on an EXPERIMENTAL AIRCRAFT.
Believe me. This works.
I had FIVE... Count them up... I say again.... FIVE FAA inspectors demanding that I had to have an Aircraft Operating Manual and a whole slew of other things. They were very authoritative, and very demanding, and totally WRONG.
The EAA cleared this issue up for me in RECORD TIME.
