NTSB narrative

Just as the helicopter touched down while performing a hovering autorotation, the certified flight instructor (CFI) heard a loud 'snap’ coming from the right side. The CFI took the controls from the student and attempted to neutralize the anti-torque pedals, but reported that they were stuck in place, with the right pedal in the forward position. He reduced the engine rpm’s to 75 percent, and attempted to move the pedals to no avail. At that point, he instructed the student to start the shutdown procedures. Following a normal shutdown, they exited the helicopter, and began to inspect the cause of the stuck anti-torque pedal. Both the CFI and student observed a broken metal structure adjacent to the restraining block that retains the anti-torque pedals. The CFI reported that it appeared to be the actual metal structure that the entire pedal assembly bolts to. The helicopter inspection revealed that the right-hand support bracket (part number A359-2) of the tail rotor control system had failed. The operator reported that the airframe had a total time of 13,000 hours. The helicopter manufacturer reported that they had been aware of other failed support brackets on helicopters with over 7,500 hours in service. As a result, the manufacturer increased the thickness of the support bracket material, and changed their overhaul procedures requiring replacement of the A359-1 and -2 support brackets at overhaul for all R22 and R44 models. The manufacturer also issued service bulletin (SB) SB-97 for the R22 and SB-63 for the R44, which require the addition of a safety tab on the older thinner support brackets.

Probable cause

Failure of the tail rotor system support bracket during landing.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status, damage. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
