Important Service Bulletins and AD's


Service Bulletin
Hawker Beechcraft SB 55-3835 - MANDATORY

GEM is currently providing compliance with the Hawker Beechcraft Service Bulletin SB 55-3835 which has now become Mandatory (per Beechcraft maintenance Manuals chapter 4). This requirement is for the addition of Vertical Spar and Horizontal Spar inspection accesses for compliance with the requirement to inspect annually for corrosion.

This requirement is for all “T” Tail KingAirs (F90, 200, 300 and 350 models) by May 1, 2012 if not already accomplished.

 

  • If your King Air is more than six years old, you need to have the inspection panel kit installed and your initial T-tail inspection performed by May 1. 2012. A very limited number of King Airs have until Nov 1, 2012, and the serial numbers of those King Airs are indicated in the "Notes" section of the bulletin.
  • If your King Air is less than six years old, it must have the kit installed and the initial inspection performed by six years from the certification date of the aircraft.

 

Have any questions about when your T-tail King Air is due for this inspection, please check the manual Chapter 4, "Airworthiness Limitations", or speak with our GEM Service Representative for assistance right away.


 

Airworthiness Directive
King Air Series - Model 200/300/B300, ATA

Horizontal and Vertical Stabilizer Inspection Limitation In 2011, Hawker Beechcraft Corporation (HBC) revised the Airworthiness Limitations Manuals for the Model 200/300/B300 airplanes.

This revision mandated the inspection of the vertical and horizontal stabilizers via the inspection panels installed by Kit 101-6003. The deadline to complete the initial inspection for most T-tail King Air models is May 1, 2012.

Contact our GEM Service Representative for more information.


 

Airworthiness Directive
Pratt & Whitney Canada Turboprop Engines

SUMMARY: We are adopting a new airworthiness directive (AD) for certain Pratt & Whitney
Canada PT6A-38, -41, -42, -42A, -61, -64, -66, -66B, -110, -112, -114, -114A, -121, -135, and -135A
series turboprop engines.

This AD requires removal from service of certain Part Manufacturer Approval (PMA) replacement Timken Alcor Aerospace Technologies, Inc. (TAATI) first stage sun gears and planet gears installed in the reduction gearbox. This AD was prompted by failures of certain first stage sun gears manufactured by TAATI. We are issuing this AD to prevent failure of the sun gear and planet gears which will result in an engine in-flight shut down, possible uncontained engine failure, aircraft damage, and serious injuries. This AD became effective May 23, 2012.


Please check back over the next week as we will be posting additional bulletins on the GEM website.
