Applicability*9

This AD applies to Aeroclubul Romaniei Model IS-28B2 gliders, all serial numbers, certificated in any category.

Compliance

Unless already done, do the following actions in paragraphs (f)(1) through (3): (1) Within 90 days after March 20, 2018 (the effective date of this AD) and repetitively thereafter at intervals not to exceed 50 hours time-in-service (TIS), inspect the rear fuselage structure following the instructions in Aeroclubul Romaniei Service Bulletin (SB) No.: SB-IS-28B2-AR-01, Revision 003, dated February 9, 2017. (2) If any crack or corrosion is detected during any inspection required in paragraph (f)(1) of this AD, before further flight, modify the rear fuselage structure following the instructions in Aeroclubul Romaniei SB No.: SB-IS-28B2-AR-02, Revision 01, dated February 24, 2017. (3) Completion of the modification to the rear fuselage structure as required in paragraph (f)(2) of this AD terminates the repetitive inspections required in paragraph (f)(1) of this AD.

Required actions

Although Aeroclubul Romaniei SB No.: SB-IS-28B2-AR-01, Revision 003, dated February 9, 2017, specifies to submit certain information to the manufacturer, this AD does not require that action.

Unsafe condition

This AD was prompted by 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 cracks at stringers in the rear fuselage of several Model IS-28B2 gliders. We are issuing this AD to detect and correct cracks, which could lead to reduced structural strength resulting in loss of structural integrity and loss of control.

Affected ADs

None.
