Mitsubishi MU-2 Operators Warned of Wing Spacer Cracks
FAA is urging MU-2 operators to perform a fluorescent penetrant inspection of the wing spacer plates for cracks and replace any cracked wing spacer plates.

The FAA has issued Special Airworthiness Information Bulletin CE-19-19 (SAIB) recommending that operators of all model Mitsubishi MU-2 twin turboprops comply, if they have not already, with three-year-old manufacturer’s Service Bulletins (SBs) that outline procedures to detect and correct cracks in the wing spacer plates. If left uncorrected, these cracks could result in reduced structural integrity of the wings, the FAA said, but added, “At this time, the airworthiness concern is not an unsafe condition that would warrant Airworthiness Directive (AD) action.”
