Technical resource content for BAS inertia reel shoulder harness systems.

Instructions for Continued Airworthiness

These ICA pertain to the inertia reel shoulder harness system installed in the 2 forward seating positions. The shoulder harness system consists of an inertia reel mounted to the aircraft cabin roof above and behind each seat, a Y shaped shoulder harness, a lap belt with mating buckle and associated bracketry and hardware to attach the system to the aircraft.

  • There is no regular servicing required for the shoulder harness system beyond normal cleaning.
  • The attachment hardware and bracketry should be inspected as part of the annual inspection of the aircraft for deformation or cracking of the bracketry and that the hardware is secure.
  • The reel should allow for extension of the harness during a slow pull, but should lock up during a quick pull of the harness.
  • The shoulder harness does not have a fixed overhaul period, but should be inspected and replaced on condition.

Installation Notes

Cessna C170, C170A, and 200 Series special installation notes.

  • Mounting nut plates were not factory-installed in carry-through spars of models C170 and C170A.
  • Factory installed mounting nut plates must be relocated approximately 2 3/4 inches outboard (or inboard, depending on year of manufacture) for 200-Series Aircraft.
  • Practice with the magnet and a nut plate on a flat sheet of aluminum. Some magnets tend to roll the nut plate rather than sliding it.
