EASA SIB CE-11-05: Taylorcraft - Main Landing Gear Tie Strut P/N B-A51

What to do

Owners and operators of Taylorcraft airplanes equipped with MLG tie strut PN B-A51 should inspect the tie strut within 30 days of receiving SAIB CE-11-05 and annually thereafter, following Taylorcraft Service Bulletin No. 78-001 and the expanded FAA recommendations. This includes checking for and clearing drain holes, inspecting for rust or debris, and performing additional inspections or non-destructive testing if corrosion is suspected. Repair or replace any corroded tie struts promptly to maintain airworthiness.

Summary

The Special Airworthiness Information Bulletin SAIB: CE-11-05 is an FAA informational bulletin addressing corrosion concerns in the main landing gear tie strut part number B-A51 installed on Taylorcraft airplanes, including models under type certificate data sheets 1A9, 1A11, TG-6, A-643, A-696, A-699, A-700, A-746, and TG-6. It provides guidance to owners and operators on inspecting and mitigating corrosion risks to prevent tie strut failure. This bulletin is not a mandatory directive but offers important safety recommendations.

What changed

SAIB CE-11-05 introduces updated inspection and maintenance recommendations for the Taylorcraft main landing gear tie strut PN B-A51, emphasizing the need to verify the presence and functionality of factory drain holes and to add drain holes if missing. It also expands on previous instructions from Taylorcraft Service Bulletin No. 78-001 by recommending additional inspection procedures and non-destructive testing if corrosion is suspected.

Why it matters

This bulletin is critical for aviation professionals because corrosion in the main landing gear tie strut can lead to structural failure and significant airframe damage, as evidenced by a 2010 incident involving a Taylorcraft BC12-D. Operators, maintenance organizations, and compliance teams must be aware of these risks to ensure continued airworthiness and safety of affected aircraft. Early detection and repair or replacement of corroded components help prevent accidents and costly repairs.
