Airworthiness Directive · Amendment 39-14245 · Bombardier Model CL-215-1A10 (Water Bomber), CL-215-6B11 (CL215T Variant), and CL-215-6B11 (CL415 Variant) Airplanes
Bombardier Model CL-215-1A10 (Water Bomber), CL-215-6B11 (CL215T Variant), and CL-215-6B11 (CL415 Variant) Airplanes
Superseded. A later AD replaced this one: AD 2012-11-04. Comply with the one in force.
This AD applies to Bombardier Model CL-215-1A10 (Water Bomber), CL-215-6B11 (CL215T Variant), and CL-215-6B11 (CL415 Variant) airplanes; certificated in any category; serial numbers 1001 through 1125 inclusive.
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Bombardier Model CL-215-1A10 and CL-215- 6B11 series airplanes. That AD currently requires repetitive ultrasonic inspections to detect cracking of the lower caps of the wing front spar and rear spar, and corrective action if necessary. This new AD reduces the threshold to do the initial inspections and revises the repetitive inspection interval. This new AD also adds a repetitive ultrasonic inspection of the wing lower skin. This AD results from reports of cracks in the front and rear spar lower caps. We are issuing this AD to detect and correct cracking of the lower caps of the wing front spar and rear spar, which could result in reduced structural integrity of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the time specified in paragraph (g) of this AD: Perform an ultrasonic inspection to detect cracking of the lower cap of the wing front and rear spars at wing station 51, in accordance with the Accomplishment Instructions of Canadair Alert Service Bulletin 215-A463, Revision 1, dated May 25, 1995, or Bombardier Alert Service Bulletin 215-A463, Revision 2, dated March 13, 2001 (for the front spar); and Canadair Alert Service Bulletin 215-A454, Revision 1, dated May 25, 1995, Bombardier Alert Service Bulletin 215-A454, Revision 2, dated January 27, 1999, or Bombardier Alert Service Bulletin 215-A454, Revision 3, dated March 13, 2001 (for the rear spar). As of the effective date of this AD, the inspection must be done in accordance with the Accomplishment Instructions of Bombardier Alert Service Bulletin 215-A463, Revision 2, dated March 13, 2001 (for the front spar); and Bombardier Alert Service Bulletin 215-A454, Revision 3, dated March 13, 2001 (for the rear spar).
(g) Do the inspections required by paragraph (f) of this AD at the earlier of the times specified in paragraphs (g)(1) and (g)(2) of this AD.
(1) Prior to the accumulation of 3,000 total flight hours, or within 25 flight hours after March 4, 1998 (the effective date of AD 98-04-08), whichever occurs later.
(2) At the later of the times specified in paragraphs (g)(2)(i) and (g)(2)(ii) of this AD.
(i) Prior to the accumulation of 2,500 total flight hours, or 8,000 total water drops, whichever occurs first.
(ii) Within 50 flight hours or 150 water drops after the effective date of this AD, whichever occurs first.
Repeat the ultrasonic inspection specified in paragraph (f) of this AD at the times specified in paragraph (h)(1) or (h)(2) of this AD, as applicable.
(1) For airplanes on which any ultrasonic inspection required by paragraph (a) of AD 98-04-08 has been done before the effective date of this AD: Within 600 flight hours after the last ultrasonic inspection, do the ultrasonic inspection specified in paragraph (f) of this AD. Repeat the ultrasonic inspection specified in paragraph (f) of this AD thereafter at intervals not to exceed 600 flight hours or 2,000 water drops, whichever occurs first.
(2) For airplanes on which the ultrasonic inspection required by paragraph (a) of AD 98-04-08 has not been done before the effective date of this AD: After accomplishing the initial ultrasonic inspection specified in paragraph (f) of this AD, repeat the ultrasonic inspection specified in paragraph (f) of this AD thereafter at intervals not to exceed 600 flight hours or 2,000 water drops, whichever occurs first.
(i) At the later of the times specified in paragraphs (i)(1) and (i)(2) of this AD, do an ultrasonic inspection for cracks of the wing lower skin, in accordance with Bombardier Alert Service Bulletin 215-A454, Revision 3, dated March 13, 2001. Thereafter, do the ultrasonic inspection for cracks of the wing lower skin at the times specified for the ultrasonic inspection in paragraph (h) of this AD.
(1) Within 50 flight hours or 150 water drops after the effective date of this AD, whichever occurs first.
(2) Before further flight after accomplishing the first ultrasonic inspection required by paragraph (f) or (h) of this AD after the effective date of this AD.
If any cracking is detected during any inspection required by paragraph (f), (h), or (i) of this AD, before further flight, accomplish paragraphs (j)(1) and (j)(2) of this AD.
(1) Rework the lower cap of the front or rear spar, as applicable, in accordance with the Accomplishment Instructions of Bombardier Alert Service Bulletin 215-A463, Revision 2, dated March 13, 2001 (for the front spar); and Bombardier Alert Service Bulletin 215-A454, Revision 3, dated March 13, 2001 (for the rear spar).
(2) After doing the rework specified in paragraph (j)(1) of this AD, do a general visual inspection, from inside the wing box, to detect cracks of the front spar web or rear spar web, as applicable, and the lower skin area, in accordance with the Accomplishment Instructions of Bombardier Alert Service Bulletin 215-A463, Revision 2, dated March 13, 2001 (for the front spar); and Bombardier Alert Service Bulletin 215-A454, Revision 3, dated March 13, 2001 (for the rear spar). If any cracking is detected, before further flight, repair in accordance with a method approved by the Manager, New York Aircraft Certification Office (ACO), FAA; or Transport Canada Civil Aviation (TCCA) (or its delegated agent).
Note 1: For the purposes of this AD, a general visual inspection is: “A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to ensure visual access to all surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.”
Actions accomplished before the effective date of this AD in accordance with Canadair Alert Service Bulletin 215-A463, dated April 8, 1993; Canadair Alert Service Bulletin 215-A463, Revision 1, dated May 25, 1995; Canadair Alert Service Bulletin 215-A454, dated October 13, 1993; Canadair Alert Service Bulletin 215-A454, Revision 1, dated May 25, 1995; and Bombardier Alert Service Bulletin 215-A454, Revision 2, dated January 27, 1999; are considered acceptable for compliance with the corresponding actions specified in this AD.

For any inspection required by this AD that is accomplished after the effective date of this AD, within 30 days after accomplishing the inspection, submit a report of any inspection results (both positive and negative findings) to Bombardier, Inc., Canadair, Aerospace Group, P.O. Box 6087, Station Centre-ville, Montreal, Quebec H3C 3G9, Canada. Under the provisions of the Paperwork Reduction Act of 1980 (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements contained in this AD, and assigned OMB Control Number 2120-0056.
