EASA AD BR-2019-11-07
Landing Gear - Pintle Pins of the Main Landing Gear Shock Struts - Inspection / Replacement
Summary
Brazilian Airworthiness Directive AD No. 2019-11-07 addresses inspection and replacement requirements for the pintle pins of the main landing gear shock struts on specific Embraer ERJ 170 and ERJ 190 series aircraft. The directive applies to certain pintle pins repaired under specific Liebherr Aerospace engineering dispositions that may have reduced life limits. It mandates inspections and replacement of affected pintle pins to ensure continued airworthiness and safety.
What Changed
This new directive introduces mandatory inspections and replacement of main landing gear aft pintle pins that have undergone sulphamate nickel plating repairs, which were found to have reduced life limits. It prohibits installation of pintle pins with such nickel repairs on the landing gear assembly. The directive specifies different compliance thresholds based on aircraft model and repair history.
Why It Matters
This directive is critical for aviation professionals because failure of the pintle pin can lead to main landing gear collapse during takeoff or landing, posing serious safety risks. Operators and maintenance teams must ensure compliance to prevent potential accidents and maintain regulatory certification. Accurate tracking of pintle pin repair status and life limits is essential for safe aircraft operation.
What To Do
Operators must inspect aircraft technical documentation and perform a general visual inspection to identify affected pintle pins before they reach specified flight cycle limits or timeframes. If affected pins are found, they must be replaced with serviceable pins without sulphamate nickel repairs. Installation of repaired pintle pins is prohibited from the effective date. Compliance deadlines vary by aircraft model, with the earliest required before 15,000 flight cycles or within 60 months for some models.
