What to do
Operators of affected Boeing DC-10, MD-10, and MD-11 series airplanes must perform the required inspections and repairs as specified in Boeing Alert Requirements Bulletins DC10-53A184 RB and MD11-53A088 RB. The initial compliance and all repetitive inspections must be completed according to the timelines in the service bulletins. This Airworthiness Directive is effective December 18, 2020, and compliance must begin by that date.
Summary
Federal Aviation Administration Airworthiness Directive 2020-22-15 is a final rule addressing all Boeing Model DC-10 and MD-10 series airplanes, as well as MD-11 and MD-11F airplanes. It mandates inspections of overwing floor beams and floor beam supports near the overwing exit doors due to reports of cracking. The directive aims to ensure structural integrity and prevent potential loss of airplane controllability.
What changed
This new airworthiness directive introduces mandatory inspections for cracked floor beams and supports at specific stations on the left and right sides of affected Boeing aircraft. It requires initial and repetitive inspections, including general visual and eddy current high frequency inspections, along with on-condition repair actions. The AD also incorporates Boeing Alert Requirements Bulletins for detailed inspection and repair procedures.
Why it matters
This directive is critical for aviation professionals because undetected cracks in overwing floor beams can compromise the structural integrity of the airplane, potentially leading to loss of primary control systems. Operators and maintenance organizations must comply to maintain airworthiness and ensure flight safety. Compliance helps prevent costly structural failures and supports regulatory adherence.
