Models named: A321-111, -112, -131, -211, -212, -213, -231, -232. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to Airbus Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes, certificated in any category.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

At the applicable time specified in table 1 to the introductory text of paragraph (g) of this AD, do a rototest inspection for cracking at frame (FR) 35.1, FR 35.2, and FR 35.3 on the LH and RH sides, in accordance with the Accomplishment Instructions of the Airbus service information specified in paragraphs (g)(1), (g)(2), (g)(3), (g)(4), (g)(5), and (g)(6) of this AD. Repeat the inspection thereafter at intervals not to exceed 5,300 flight cycles. Table 1 to the Introductory Text of Paragraph ( g ) of This AD—Inspection Threshold Airplane accumulated total flight cycles at the effective date of this AD Compliance time For airplanes with 18,300 total flight cycles or less Before exceeding 18,300 total flight cycles, or within 5,300 flight cycles after the effective date of this AD, whichever occurs later. For airplanes with more than 18,300 total flight cycles Before exceeding 23,600 total flight cycles, or within 2,100 flight cycles after the effective date of this AD, whichever occurs later.

(3) Airbus Service Bulletin A320-53-1310, dated November 4, 2015 (FR 35.2 LH side). (4) Airbus Service Bulletin A320-53-1311, dated November 4, 2015 (FR 35.2 RH side). (5) Airbus Service Bulletin A320-53-1312, dated November 4, 2015 (FR 35.3 LH side). (6) Airbus Service Bulletin A320-53-1313, dated November 4, 2015 (FR 35.3 RH side).

Unsafe condition

This AD was prompted by a full scale fatigue test campaign on Airbus Model A321 series airplanes in the context of the extended service goal. It was determined that cracks could develop on the fastener holes of certain frames on the left-hand (LH) and right-hand (RH) sides of the affected airplanes. We are issuing this AD to detect and correct cracking of the fastener holes at certain frame locations, which could result in reduced structural integrity of the fuselage.

Affected ADs

None.
