2009-18-20: We are adopting a new airworthiness directive (AD) for the products listed above. This 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: One Long Range operator experienced a failure of one spoiler servo-control, associated with surface deflection in flight and hydraulic leak. On ground, this servo-control Part Number (P/N) MZ4306000-02X was found with the maintenance cover broken. Investigations showed that the rupture of the maintenance cover was due to pressure pulse fatigue. * * * The rupture of the maintenance cover in flight may result in the deflection of the associated spoiler surface up to the null- hinge position (loss of the hydraulic locking). It may also result in the loss of the associated hydraulic system (external leakage). In the worst case, the three hydraulic systems may be affected, which constitutes an unsafe condition. * * * * * Loss of the three hydraulic systems could result in reduced controllability of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.

2009-25-01: We are adopting a new airworthiness directive (AD) to supersede AD 91-18-19, which applies to certain Hawker Beechcraft Corporation (Hawker) (Type Certificate Numbers 3A15, 3A16, and A23CE formerly held by Raytheon Aircraft Company; formerly held by Beech Aircraft Corporation) Models 58, 58A, 58P, 58PA, 58TC, 58TCA, 95-B55, 95-B55A, A36, A36TC, B36TC, E55, E55A, F33A, and V35B airplanes. AD 91- 18-19 currently requires you to do a one-time inspection of the pilot and copilot shoulder harnesses for an incorrect washer and replace any incorrect washer with the correct washer. Since we issued AD 91-18-19, we have found that the applicability of AD 91-18-19 was incorrectly stated when the Model A36TC airplane was omitted from the Applicability section. Consequently, this AD would retain the actions and the serial number (SN) applicability of AD 91-18-19 and realign the SN applicability for Models A36TC and B36TC airplanes. We are issuing this AD to detect and correct an incorrectwasher installed in the pilot and copilot shoulder harnesses. This incorrect part could result in a malfunctioning shoulder harness. Such a malfunction could lead to occupant injury.
