Inspection required after each 100 hours of operation.
Inspect the front and rear canvas seat installations and note the condition of canvas, eyelets, and lacing. Any parts showing signs of wear, tearing, fraying or substandard material the failure of which could cause possible interference with the control system should be replaced. Check the tautness of the canvas to insure that position clearance with all parts of the elevator control system exists when the seats are occupied.
