From Communiqué # ME-TP-001: Multi-Engine Turboprop Communiqué
Issued: February 2017
ATA 00 – General Introduction
Beechcraft and Hawker customers will notice a change in the formatting and document numbering of Model Communiqués. In an effort to streamline the brands, Textron Aviation is changing the airplane specific Model Communiqués to a broader grouping. For example, the previous King Air Model Communiqués are now the Multi-Engine Turboprop Communiqués (document reference number ME-TP-XXX). The Multi-Engine Turboprop (ME-TP-XXX) grouping applies to the King Air, Conquest I and II, and Beechcraft Commuter. The Single Engine Turboprop (SE-TP-XXX) grouping applies to the Caravan and Denali. Please note that because of this change, some communiqués may still only apply to one specific brand but will be sent to all airplanes that are covered by the Multi-Engine Turboprop heading.
ATA 11 – King Air 250 and 350 Winglet Placard
BY-122, BY-124 and after; BZ-1 and after; FL-1 and after, FM-1 and after
The King Air 250 placard installed on the outboard side of the winglets does not have an official published part number. If the placard needs to be replaced, please place your order for the replacement via email to parts_research@txtav.com.
The transaction and billing for the placard
will be made through the Technical Manual Distribution Center.
ATA 26 – Engine Fire Extinguisher Connections - Revisited
King Air Communiqué 2009-05 provided a caution in connecting the engine fire extinguisher wires to the squib to assure that the system operates as it should. This Communiqué read:
“Caution should be exercised when attaching the airplane’s wiring to the fire extinguisher squibs. The power wire should be connected to the terminal on the insulated end of the squib. The ground wire and the sensor should be connected to the side terminal. Incorrect attachment of the wiring can result in the cockpit fire extinguisher testing ‘OK’ but not firing the squib and causing the circuit breaker to open in the event of the extinguisher button being pushed.”
We would like to emphasize that if the wires are connected incorrectly the extinguisher test would still test ok, but if the flight crew needed to discharge the bottle the circuit breaker would open instead.
We have included an additional illustration and picture showing the correct connections along with procedures to verify the correct installation of each extinguisher squib wire terminals. (Editor’s Note: Illustration and picture included on the original Communiqué found online.)
Procedures:
1. For each engine fire bottle squibs the 28 VDC power wire shall be
verified by connecting a 28 VDC test light lead to the removed squib MARCH 2017
