one-timeAirworthiness Directives; or reworked between June 20, 1985, and December 31, 1985, and there is not a "-R" after the serial number of the fire extinguisher
Which aircraft AD 85-22-03 applies to
Fire extinguisher containers manufactured or reworked between June 20, 1985 and December 31, 1985 that lack a '-R' suffix after the serial number must be removed and replaced with a serviceable unit before further flight, unless determined serviceable.
