AI-generated summary of the official EASA document. Verify against the PDF before acting.
What to do
Operators and maintainers of Piper PA-31 series aircraft should urgently review the installation of wing leading edge stall strips to confirm they match the correct configuration for their aircraft's model and serial number. If stall strips have been removed without marking their positions, assistance from a Piper dealer should be sought to ensure accurate reinstallation. No mandatory compliance deadline is specified, but prompt action is recommended to maintain Type Design conformity.
Summary
EASA Safety Information Bulletin 2010-09R1 is an advisory document addressing the wing leading edge stall strip configuration for Piper PA-31 series aircraft, including PA-31, PA-31-300, PA-31-325, and PA-31-350 models. It highlights the importance of correct stall strip installation to maintain conformity with the aircraft's Type Design and improve low-speed handling characteristics. The bulletin supports CASA Australia's Airworthiness Bulletin 57-009 Issue 2 and provides guidance for European operators and maintainers.
What changed
This bulletin endorses CASA's updated advisory which clarifies the correct wing leading edge stall strip configurations based on airframe model and serial number ranges rather than wing locker installation. It also notes Piper's intention to revise the Illustrated Parts Catalogue to correct previous inaccuracies linking stall strip installation to wing locker configuration. The bulletin includes detailed stall strip installation configurations and stresses the criticality of precise stall strip positioning.
Why it matters
Proper installation of wing leading edge stall strips is essential for the safe low-speed handling of Piper PA-31 series aircraft and to ensure compliance with the Type Design. Incorrect or missing stall strips can compromise flight safety and regulatory conformity, potentially leading to operational restrictions or increased maintenance scrutiny. Operators, maintainers, and compliance teams must be aware of these requirements to avoid inadvertent non-compliance and maintain aircraft airworthiness.
