2007-03-19 Bombardier, Inc. (Formerly Canadair): Amendment 39-14930. Docket No. FAA-
2006-25192; Directorate Identifier 2006-NM-004-AD.
Effective Date
(a) This AD becomes effective March 15, 2007.
Affected ADs
(b) This AD supersedes AD 2004-14-16.
Applicability
(c) This AD applies to Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440)
airplanes, serial numbers 7003 and subsequent; certificated in any category; equipped with main
landing gear (MLG) main fittings, part numbers (P/N) 601R85001-81 and 601R85001-82 (Messier
Dowty Incorporated P/Ns 17064-105 and 17064-106).
Unsafe Condition
(d) This AD results from stress analyses that showed certain main fittings of the MLGs are
susceptible to premature cracking, starting in the radius of the upper lug. We are issuing this AD to
detect and correct premature cracking of the main fittings of the MLGs, which could result in failure
of the fittings and consequent collapse of the MLGs during landing.
Compliance
(e) You are responsible for having the actions required by this AD performed within the
compliance times specified, unless the actions have already been done.
Restatement of the Requirements of AD 2004-14-16

(f) Before the accumulation of 2,500 total flight cycles on the MLGs, or within 250 flight cycles
after August 13, 2004 (the effective date of AD 2004-14-16), whichever occurs later: Do a detailed
inspection on the main fittings of the MLGs to detect discrepancies (i.e., linear paint cracks or lack of
paint (paint peeling), any other paint damage, adhesion, paint bulging, or corrosion), in accordance
with Part A of the Accomplishment Instructions of Bombardier Alert Service Bulletin (ASB) A601R-
32-088, dated February 20, 2003; or Bombardier ASB 601R-32-088, Revision A, dated June 16,
