Re: Customer Notice
Subject: Joystick Revision, Two Place Commander
To: All Owners /Operators of Two Place Air Command Gyroplanes, both Side-by-Side and Tandem Configurations
From: Harold F. Smith, President
This bulletin is recommended as an immediate correction to a potential flight safety problem concerning the joystick on two place Air Command Gyroplanes. The aluminum joysticks should be removed and discarded, and a new joystick fabricated from 4130 steel tubing with a wall thickness of 0.058". The reason for this action is the heavier machines import heavier control system loads, and there is potential to exceed the safe life of aluminum 6061-T6 joysticks. A note should be entered in the aircraft records that this bulletin has been completed when the joystick is changed to 4130. Owners and operators not having access to 4130 steel tubing with a 0.058" wall, may order raw material or a finished replacement part from Air Command. Future production kits will incorporate this change.
