EASA AD ISR-I-04-2020-06-02R1
Temporary Limitations and Inspection Requirements of the Section 05-10-10 Airworthiness Limitations Section - Airplane Maintenance Manual Revision
Summary
Airworthiness Directive ISR-I-04-2020-06-02_R1 is issued by the State of Israel Civil Aviation Authority and applies to all Gulfstream Aerospace LP Model G280 aircraft. This directive addresses a revision to the Airworthiness Limitations Section of the G280 Airplane Maintenance Manual, specifically adding a new inspection task related to the Horizontal Stabilizer Trim Actuator. The directive aims to enhance safety by mandating increased inspection frequency due to potential solder cracking in certain Flight Control Electronic Control Units.
What Changed
The directive introduces the incorporation of inspection task "AWL-3" for the Horizontal Stabilizer Trim Actuator No-Back Operational Check into Table 9 of Section 05-10-10 of the G280 Airplane Maintenance Manual. This task is a temporary limitation and inspection requirement added to address the risk of solder cracking in specific Flight Control Electronic Control Units. The change mandates operators to increase inspection frequency until affected units are replaced.
Why It Matters
This directive is critical for aviation professionals because it addresses a latent failure mode that could lead to uncontrolled operation of the Horizontal Stabilizer Trim Actuator, posing a significant safety risk. Operators and maintenance organizations must comply to maintain certification safety objectives and ensure continued airworthiness of the G280 fleet. Compliance helps prevent potential in-flight control issues and supports regulatory adherence.
What To Do
Operators of Gulfstream G280 aircraft must incorporate the new inspection task "AWL-3" into their maintenance programs within 90 days of the directive's effective date. This involves updating the Airworthiness Limitations Section of the maintenance manual and performing the increased frequency inspections as specified. The compliance deadline for these actions is February 15, 2021.
