EASA SIB CE-14-23
Piper PA-28, PA-32, PA-34, PA-44 and PA-46 Aeroplanes — Air Inlet Hose
Summary
The Special Airworthiness Information Bulletin SAIB: CE-14-23 is an FAA informational bulletin addressing an airworthiness concern for Piper Aircraft Models PA-28, PA-32, PA-34, PA-44, and PA-46 series airplanes. It highlights the risk of structural deterioration and possible collapse of the air inlet hose, which can reduce engine airflow and cause rough running or power loss. The bulletin does not mandate corrective action but provides important safety information for these Piper models.
What Changed
This bulletin introduces awareness of the potential for air inlet hose collapse in specified Piper aircraft models and recommends inspection and replacement if necessary. It identifies that some installed hoses may not be approved parts and may lack the proper internal support, increasing the risk of failure. No new regulatory mandates or Airworthiness Directives are issued at this time.
Why It Matters
This matters because a collapsed or deteriorated air inlet hose can restrict engine airflow, leading to engine power loss or rough operation, which poses a safety risk during flight. Operators, maintenance personnel, and compliance teams need to be aware of this issue to prevent accidents and ensure continued airworthiness. Early detection and replacement of non-approved or damaged hoses can mitigate potential engine performance problems.
What To Do
Owners, operators, and maintenance personnel of Piper PA-28, PA-32, PA-34, PA-44, and PA-46 airplanes should inspect the air inlet hose within the next 25 hours of flight time. They must verify the hose is an approved Piper part and check for broken cords, displaced support wire, wear, perforation, deterioration, or collapse. If any issues are found or the hose is not approved, it should be replaced with an approved Piper part before the next flight.
