Airworthiness Directive · Amendment 39-19190 · Fuselage
Aeroclubul Romaniei Gliders
This AD applies to Aeroclubul Romaniei Model IS-28B2 gliders, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for Aeroclubul Romaniei Model IS-28B2 gliders. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 require actions to address the unsafe condition on these products.
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.
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.
