Textron Aviation Model Communiqué Updates – King Air 90


Textron Aviation Model Communiqué Updates – King Air 90

Wichita, KS (May 2015) – Textron Aviation has recently issued several new Model Communiqués for their King Air series aircraft. Below are the most recent MCs relating to the 90 series King Airs.

Issued July 2014, MC-KA-2014-01 documents the difference in the outboard wing deice boots on the King Air C90GTx, versus the previous 90 series King Airs. As a result of the installation of winglets on the GTx aircraft, plus a few other minor changes to the structure, there is a distinct part number for GTx outboard deice boots.

Several operators have reported damage to the wire terminal adapters on the starter generators on the PT6 engines installed on all versions of King Air 90 aircraft. According to MC-KA-2014-02, issued October 2014, incorrect nuts were being used to secure these terminal adapters. The correct part is MS21083N, which is a black self-locking nut. The previously used steel nuts will cause stripping of the attachment bolts.

Beginning in 2014, “how to” videos have been created for Beechcraft and Hawker model aircraft. The videos are available directly on YouTube, or through a series of QR (quick response) codes included in certain technical documents. Scanning of these QR codes with a smart phone or similar device will take you to the related video. Communiqué MC-KA-2014-03 or www.txtavsupport.com has more information on the QR codes and the Beechcraft “how to” videos, as well as model specific pages.

Early in 2015, MC-KA-2015-01 was issued detailing several newly found maintenance issues. First and most importantly relates to ATA 27 – lower rudder attach bolts. Several aircraft have been found to have the bolt securing the rudder horn assembly bent while in service. This communiqué emphasizes the importance of locking the rudder when the aircraft is parked, as well as periodic inspections for bent bolts.

MC-KA-2015-01 also has a noticed related to changes to ATA 33 with the introduction of LED taxi and landing light kits, and ATA 61, detailing the availability of Propeller Synchronization test equipment for rental from www.propsyncsolutions.com.
