SAIB CE-08-06 Current Issued 11/14/2007 Schleicher, Alexander, GmgH & Co. ASW-28

What is a SAIB?

A Special Airworthiness Information Bulletin is an FAA-issued advisory — not mandatory like an AD, but worth knowing about. SAIBs typically flag service bulletins, manufacturer recommendations, or emerging issues that don't (yet) rise to AD level.

FAA Aircraft Certification Service SPECIAL AIRWORTHINESS INFORMATION BULLETIN SUBJ: Engine Fuel and Control SAIB: CE-08-06 Date: November 14, 2007 This is information only. Recommendations aren’t mandatory.

Introduction

This Special Airworthiness Information Bulletin informs you of an airworthiness concern for Alexander Schleicher powered sailplane Model ASW 28-18E, all serial numbers up to 28742 inclusive. The European Aviation Safety Agency (EASA) has issued emergency airworthiness directive (AD) number 2007-0042, dated February 21, 2007, for those sailplanes registered for operation in Europe. That AD is based on Alexander Schleicher Technical Note No. 2, dated September 1, 2006; EASA approved on November 13, 2006.

Background

During manufacturer inspections, cracks were found on the RPM sensor and fuel pump attachment plates. These cracks could lead to loose parts, which may adversely affect engine operation. For airplanes operating in Europe, the EASA AD requires replacing the RPM sensor and fuel pump attachment plates, updating the engine instrument hardware, and replacing a page in the flight manual.

Recommendations

These sailplanes are not type certificated in the United States and, therefore, the condition is not addressed by FAA AD action. However, these sailplanes could be operating in the United States with an experimental airworthiness certificate or other means. We recommend all owners and operators comply with actions outlined in Alexander Schleicher Technical Note No. 2.
