Airworthiness Directive · Amendment 39-13942 · EXTRA Flugzeugbau GmbH Model EA-300 and EA-300/S Airplanes
EXTRA Flugzeugbau GmbH Model EA-300 and EA-300/S Airplanes
This AD affects the following airplane models and serial numbers that:
(1) Are certificated in any category; and
(2) Have not had the left-hand (LH) and right-hand (RH) upper longeron cutout-bridge inspected and modified following EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: A, Date: January 12, 1994.
| Model | Serial Nos. |
|---|---|
| EA-300 | VI and 01 through 50. |
| EA-300/S | 01 through 17. |
The FAA adopts a new airworthiness directive (AD) to supersede AD 98-03-14, which applies to certain EXTRA Flugzeugbau GmbH (EXTRA) Model EA-300 and EA-300/S airplanes. AD 98-03-14 currently requires you to inspect the upper longeron cutout-bridge for cracks, to repair any cracks found, and to modify this area. This AD retains the actions of AD 98-03-14 and incorporates new service information. For owner/ operators of the affected airplanes that were able to do the modification required in AD 98-03-14, no further action is required. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to detect and correct cracks in the upper longeron cutout-bridge, which could cause the upper longeron cutout-bridge to fail resulting in structural damage to the fuselage. This condition could lead to loss of control of the airplane.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Inspect the LH and RH upper longeron cutout-bridge, part number (P/N) PC-23102.IX), for cracks | Upon accumulating 1,000 hours time-in-service (TIS) on the upper longeron or within the next 100 hours TIS after March 16, 1998 (the effective date of AD 98-03-14), whichever occurs later, unless already done | Follow EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: A, Date: January 12, 1994; or EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: B, Date: June 10, 1998. |
| (2) If you find any cracks in the upper longeron cutout-bridge during the inspection required in paragraph (e)(1) of this AD, do the following: (i) repair any cracks; and (ii) modify the upper longeron cutout-bridge. | Before further flight after the inspection required in paragraph (e)(1) of this AD, unless already done | Follow EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: A, Date: January 12, 1994; or EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: B, Date: June 10, 1998. |
| (3) If you do not find any cracks in the upper longeron cutout-bridge during the inspection required in paragraph (e)(1) of this AD, you must still modify the upper longeron cutout-bridge | Before further flight after the inspection required in paragraph (e)(1) of this AD, unless already done | Follow EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300300/S Doc: SB300-3-93, Issue: A, Date: January 12, 1994; or EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: B, Date: June 10, 1998. |
| (4) If you modified the upper longeron cutout-bridge following EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: A, Date: January 12, 1994, or EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: B, Date: June 10, 1998, Procedure I, you do not need to do any further actions | As of February 28, 2005 (the effective date of this AD) | As stated in EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: A, Date: January 12, 1994, or EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: B, Date: June 10, 1998. |
| (5) If you modified the upper longeron cutout-bridge following Procedure II of EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: B, Date: June 10, 1998, you must replace the new internal bridges every 1,000 hours TIS | As of February 28, 2005 (the effective date of this AD) | As stated in EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: B, Date: June 10, 1998. |
