Initial response
Date issued: 23 May 2000
Response from: Federal Aviation Administration (FAA)
Response text:

We have conducted our evaluation concerning the Cessna model 300/400 series airplanes that are the subject of FAA Safety Recommendation 00.003. Because of a number of incidents in which trim-tab actuator jackscrews have 'jumped' threads, Safety Recommendation 00.003 suggests that Cessna Aircraft Corporation take appropriate action to ensure that Cessna elevator trim-tab actuator component parts affected by this safety deficiency are recoded so that they cannot be purchased separately. In addition, it is recommended that Cessna Aircraft Corporation review comparable designed trim-tab actuators to ensure that they are not affected by this safety deficiency.

After bringing this information to their attention, Cessna Aircraft Corporation agreed to recode all parts affected by this safety deficiency. The attached letters present Cessna's position on this matter (Note: letters are response from Cessna to ATSB). As a result of the Cessna's cooperation, the Wichita Aircraft Certification Office does not deem any further action to be necessary.

We recommend Safety Recommendation 00.003 be closed.
