Airworthiness Directive · Amendment 39-22646 · Wing, rib/bulkhead
WACO Classic Aircraft Corporation Airplanes
This AD applies to WACO Classic Aircraft Corporation Model 2T-1A-2 airplanes, serial numbers 1200 and subsequent with the 30116-100 upper wing center section assembly configuration, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain WACO Classic Aircraft Corporation Model 2T-1A-2 airplanes. This AD was prompted by reports of multiple types of cracks at the leading edge former ribs and trailing edge former ribs in the upper wing center section. This AD requires installing maneuver restriction placards in the front and rear cockpits, inspecting the leading and trailing edge former ribs for cracking, replacing any cracked ribs, modifying the upper wing center section assembly, and removing the maneuver restriction placards after completing the modification. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Within 30 days after the effective date of this AD, insert maneuver restriction placards on the instrument panel of the front and rear cockpits, and next to the operating placard in the rear cockpit, stating “NO AEROBATIC MANEUVERS ALLOWED.”
(2) Within 100 hours time-in-service (TIS) or within 12 months after the effective date of this AD, whichever occurs first, accomplish the following:
(i) Inspect the leading edge former ribs and trailing edge former ribs in the upper wing center section for cracking in accordance with section B and before further flight, replace any cracked rib in accordance with section C of the Accomplishment Instructions in WACO Great Lakes 2T-1A-2 Service Bulletin GL-SB0002, Revision NR, dated July 6, 2023 (WACO SB 2T-1A-2, Revision NR). Although section B of the Accomplishment Instructions in WACO SB 2T-1A-2, Revision NR, specifies to record the locations of all identified cracks found on the leading edge former ribs and the trailing edge former ribs and share this information with WACO Aircraft, this AD does not require those actions.
(ii) Modify the center section to the 30116-104 upper wing center section assembly configuration in accordance with section C of the Accomplishment Instructions in WACO SB 2T-1A-2, Revision NR.
(3) After replacing all cracked ribs and modifying the center section to the 30116-104 upper wing center section assembly configuration, aerobatic maneuvers can resume and the “NO AEROBATIC MANEUVERS ALLOWED” maneuver restriction placards can be removed from the front and rear cockpits.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
