## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

Compass mismatch (up to loss of heading information) were reported by operators, due to ferro-magnetic masses (like the telescopic Tow-Bar) stowed in the baggage compartment. A limitation was added to the approved Airplane Flight Manual, stating that the towing bar P/N 01-1227-0000 or similar ferromagnetic masses are prohibited to be carried in the baggage compartment.

Temporary Change No. 7 to the Pilot's Operating Handbook and EASA Approved Airplane Flight Manual Rep. 6591, issued: February 24, 2009, include MCAI that has maintenance requirements and/or airworthiness limitations developed by Piaggio Aero Industries S.p.A. and PiaggioAero Industries. These revisions are approved and considered mandatory by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. Failure to comply with the MCAI constitutes an unsafe condition. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
