Unsafe Condition
Failure of the main landing gear (MLG) sidestay upper arm assembly due to fatigue cracking could result in collapse of the MLG during landing, leading to loss of control of the airplane.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Replace the MLG sidestay upper arm assembly prior to 12,000 landings or within 9 months after January 27, 1993, whichever is later. Subsequent replacements must occur before 12,000 landings on each assembly. Overhauled assemblies without recorded landings must be assumed to have 8,000 landings at installation.
AI-generated summary from the source AD text. Verify against the official source before acting.
Compliance Time
Prior to the accumulation of 12,000 landings on any MLG sidestay upper arm assembly, or within 9 months after the effective date of this AD, whichever occurs later.
