EXTENSION OF SERVICE LIFE
CANCELLED - Refer Type Certificate Holders current data
Fatigue tests on fibre composite wings and wing spars have demonstrated that a service life expectancy of 12000 hours can be reached for these structural components. As these fatigue test programs did not examine the entire aircraft made of fibre composite, the service life of 12000 hours can be granted only if the long-term airworthiness of each individual aircraft is demonstrated in a special multi-stage inspection program (over and above the mandatory annual C of A inspections) for the purpose of increasing the service life. This has to be incorporated in the Maintenance Manual. This directive is applicable to the Ventus a, Ventus b, Ventus a/16.6, Ventus b/16.6, Ventus b/16 and Ventus c, all serial numbers. Schempp-Hirth Flugzeugbau GmbH Technical Note No. 349-24 TN No. 349-24 forms part of this AD.
