(d) Subject
Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 53, Fuselage.
(e) Unsafe Condition
This AD was prompted by a report that a fully cracked lower forward carry through spar cap was found on a Textron Model 402C airplane. We are issuing this AD to prevent failure of the carry through spar cap during flight. The unsafe condition, if not addressed, could result in loss of control.
(f) Compliance
Comply with this AD within the compliance times specified, unless already done.
(g) Initial Inspection for All Affected Airplanes With 24,975 Hours Time-In-Service (TIS) or More on the Carry Through Spars
Within the next 25 hours TIS after February 28, 2018 (the effective date of this
[[Page 6117]]
AD), do a detailed visual inspection of the left and right forward lower carry through spar cap for cracks. Using a 10X magnifier visually inspect the bottom surface of the carry through spar cap in the areas around the fasteners located just inboard of the left-hand and right-hand forward lower wing fittings. If a crack is not positively identified during the detailed visual inspection but is suspected or the area is questionable, before further flight, do a surface eddy current inspection of the suspected area. Do these inspections using the Accomplishment Instructions in Textron Aviation Multi-engine Mandatory Service Letter MEL-57-01 and Textron Aviation Conquest Mandatory Service Letter CQL-57-01, both dated December 18, 2017, as applicable.
(h) Initial Inspection for All Affected Airplanes With Less Than 24,975 Hours TIS on the Carry Through Spars
Using the compliance times listed in paragraphs (h)(1) through (3) of this AD, do a detailed visual inspection of the left and right forward lower carry through spar cap for cracks. Using a 10X magnifier visually inspect the bottom surface of the carry through spar cap in the areas around the fasteners located just inboard of the left-hand and right-hand forward lower wing fittings. If a crack is not positively identified during the detailed visual inspection but is suspected or the area is questionable, before further flight, do a surface eddy current inspection of the suspected area. Do these inspections using the Accomplishment Instructions in Textron Aviation Multi-engine Mandatory Service Letter MEL-57-01 and Textron Aviation Conquest Mandatory Service Letter CQL-57-01, both dated December 18, 2017, as applicable.
(1) For Models 401, 401A, 401B, 402, 402A, 402B, 402C, 411, 411A, 414, 414A, 421, and 421A airplanes: Before the accumulation of 15,000 TIS on the carry through spars or within the next 50 hours TIS after February 28, 2018 (the effective date of this AD), whichever occurs later.
(2) For Models 421B and 421C airplanes: Before the accumulation of 12,000 hours TIS on the carry through spars or within the next 50 hours TIS after February 28, 2018 (the effective date of this AD), whichever occurs later.
(3) For Model 425 airplanes: Before the accumulation of 11,000 TIS on the carry through spars or within the next 50 hours TIS after February 28, 2018 (the effective date of this AD), whichever occurs later.
(i) Repetitive Inspections for All Affected Airplanes
If no cracks are found during the detailed visual inspections or the surface eddy current inspections required in paragraphs (g) and (h) of this AD, repetitively thereafter inspect at intervals not to exceed 50 hours TIS. Inspect as specified in paragraphs (g) and (h) of this AD using the service information specified in each paragraph as applicable.
(j) Replacement of Carry Through Spars for All Affected AirplanesIf cracks are found during any inspection required in paragraphs (g) through (i) and paragraph (k) of this AD, before further flight, replace the carry through spar.
(k) Initial and Repetitive Inspections of Newly Replaced Carry Through Spars for All Affected Airplanes
At the compliance times in paragraphs (k)(1) through (3) of this AD, do a detailed visual inspection of the left and right forward lower carry through spar cap for cracks. Using a 10X magnifier visually inspect the bottom surface of the carry through spar cap in the areas around the fasteners located just inboard of the left-hand and right-hand forward lower wing fittings. If a crack is not positively identified during the detailed visual inspection but is suspected or the area is questionable, before further flight, do a surface eddy current inspection of the suspected area. Do these inspections using the Accomplishment Instructions in Textron Aviation Multi-engine Mandatory Service Letter MEL-57-01 and Textron Aviation Conquest Mandatory Service Letter CQL-57-01, both dated December 18, 2017, as applicable.
