EASA AD US-2019-21-08: Superseded by FAA AD 2019-23-10

What to do

Affected operators must inspect the forward and aft right aileron flight control cable end fittings within 30 days of November 22, 2019, the effective date of the AD. Any cable assembly found to be damaged must be replaced promptly. Operators should also submit any comments or data regarding the AD to the FAA by December 23, 2019.

Summary

FAA Airworthiness Directive 2019-21-08 is a final rule addressing Textron Aviation Inc. airplanes, including Models E33, E33A, E33C, F33, G33, 35-C33, 35-C33A, K35, M35, N35, P35, S35, V35, V35A, 36, and certain serial-numbered Models F33A, F33C, V35B, and A36. This directive mandates inspection and replacement of damaged right aileron flight control cable end fittings to prevent potential failure. The AD aims to enhance flight safety by mitigating risks associated with cracked or fractured cable fittings.

What changed

This new airworthiness directive introduces mandatory inspections of the right aileron flight control cable end fittings for corrosion, pitting, and cracks, with required replacement of any damaged cable assemblies. It applies to a broad range of Textron Aviation Inc. airplane models and serial numbers and establishes a compliance timeframe of 30 days from the effective date. The AD was issued without prior public comment due to the urgency of the unsafe condition.

Why it matters

This AD is critical for aviation professionals as it addresses a safety risk that could lead to un-commanded right roll and loss of roll control, potentially resulting in loss of airplane control. Operators and maintenance organizations must prioritize inspections and repairs to ensure continued airworthiness and compliance with FAA regulations. Timely compliance reduces the risk of in-flight control failures and enhances overall flight safety.
