Plain English Summary

3/10 complexity

This Airworthiness Directive requires operators of specific Beechcraft Model 65, 65-B80 and 70 serial numbers to inspect elevator skin assemblies following Raytheon Mandatory Service Bulletin 27-3396 and to replace any affected assemblies before further flight; the inspection must be done by 28 January 2001. The rule responds to reports that some elevator skins missed a 250°F bake after corrosion treatment, which can weaken the bond and risk skin separation. Operators pay for inspections and any replacements and may have aircraft grounded until corrected.

AD/BEECH 65/68 Magnesium Metal Bonded Elevator Assembly 13/2000

Applicability: Model Serial Numbers

A65 LC-265 through LC-272 and LC-325 through LC-335 A65-8200 LC-273 through LC-324

65-B80 LD-349 through LD-511

70 LB-1 through LB-35

Requirement: Action in accordance with Raytheon Aircraft Mandatory Service Bulletin 27-3396, Issued May 2000, Revised June 2000.

Note: FAA AD 2000-18-02 Amdt 39-11887 refers.

Compliance: Accomplish, before 28 January 2001, the check to determine whether an affected elevator skin assembly is installed. Replace, before further flight, any elevator skin assembly found to be affected.

This Airworthiness Directive becomes effective on 28 December 2000.

Background: The FAA received reports that certain elevator skin assemblies did not receive a 250 degree Fahrenheit bake operation after corrosion treatment; thus making the skin susceptible to separation from the elevator assembly. Static strength capability is reduced due to the bond degradation, and continued operation could result in skin separation with potential aircraft flutter, and consequent loss of control of the aircraft.
