For February 2017, Beechcraft has released Multi-Engine Turboprop Communiqué – ME-TP-001. The full communiqué can be found here. Sub-sections include the following:
00: General Introduction – model communique formatting and numbering has changed. 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.
11: King Air 250 and 350 Winglet Placard – 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 email@example.com.
26: Engine Fire Extinguisher Connections – Revisited – concerning fire extinguishers – 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
30: King Air 250 Propeller De-ice Boot Protection Circuit Kit – BB-1509 and after; BL-141 and after; BY-1 and after; BZ-1 and after with
Composite Propeller Blade STC SA02130SE King Air Communiqué 2015-07 described a condition in which severe damage to the propeller de-ice boots can occur if the Prop De-Ice system was left ON with the engines not running. Textron Aviation has developed a kit in which power is prevented from reaching the de-ice boots if the Prop De-Ice system is left in the ON position. The part number of the kit is 101-3301-0001.
52: Emergency Exit Door Handle Spring – Due to issues on some King Air 300/B300 and 200/B200 Series aircraft where the emergency exit exterior door handle was reported as not fitting flush with the door, Textron Aviation has approved use of a spring that provides more tension for holding the handle flush. The original 100942H0016-16 spring can be replaced with a 100942H0016-12 that has less active coils and provides more tension for the door handle to stay flush. This spares option will be added to the applicable Illustrated Parts Catalog in future revisions.
61: Additional Low Pitch Solenoid Cleaning – While troubleshooting the ground idle solenoid it is beneficial to clean any possible
contaminants from the internal bore of the solenoid. The full communique has a step by step guide for cleaning.
