AD 2017-14-16 Airworthiness Directives; Bombardier, Inc., Airplanes
Models named: BD-100-1A10. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category, serial numbers 20001 through 20433 inclusive.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Before the accumulation of 7,500 total flight cycles, or within 10 days after the effective date of this AD, whichever occurs later, do the actions required by paragraphs (g)(1) through (g)(4) of this AD, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 100-53-32, dated February 16, 2017. (1) Remove the fasteners attaching the machined center fitting (part number 1005340715), wing-to-fuselage attachment and splice fitting at fuselage station 587, to the rear spar frame lower flange splice. (2) Do a general visual inspection of the fasteners for damage and an eddy current inspection of the fastener holes for damage. (3) Rework the fastener holes as applicable. (4) Replace the fasteners with self-aligning fasteners and self-aligning collars.
Unsafe condition
This AD was prompted by a report indicating that certain fasteners attaching the machined rear spar center fitting to the frame were installed with a gap between the fastener head and the structure, or were installed tilted. We are issuing this AD to prevent failure of the fitting fasteners and consequent cracking within the fitting or frame, which could result in reduced structural integrity of the wing-to-fuselage attachment.
Affected ADs
None.
