             Cessna Aircraft Company    Single Engine Service Bulletin SB07-22-01  04 June 2007

             Note 2:  FAA AD 2008-02-06; Amendment 39-15336, dated 11 January 2008 refers.
Compliance:  For Requirement 1:  Within the next 100 hours time-in-service (TIS) or within the next 3 months after the effective date of this AD, whichever occurs first.

             For Requirement 2:  Before further flight after the Requirement 1 inspection.
             This Airworthiness Directive becomes effective on 26 February 2008.
Background:  This AD results from reports of certain GARMIN GSM 85 servo gearbox units that have foreign object debris inside the assembly.  This AD is issued to detect and correct defective GARMIN GSM 85 servo gearbox units, which could result in jamming of the servo gearbox.  This jamming could lead to the pilot having to apply sufficient control force to override the servo gearbox slip clutch in order to control the aeroplane.  In certain situations, this could compromise the safety of the aeroplane if the pilot was not able to focus on critical duties due to having to tend to the servo gearbox.
