Checking Tail Rotor Clearance
WARNING
Using a Bambi Bucket with insufficient tail rotor clearance could result in a tail rotor strike which
could result in serious injury or death.
When a Bambi Bucket is attached directly to the helicopter cargo hook or attached using a longline less
than 50 ft (15 m) in length, it is important to confirm that there is adequate tail rotor clearance. Before
using the Bambi Bucket, check the tail rotor clearance.
1. Determine the tail rotor length by measuring the distance from the cargo hook to the closest
point on the helicopter tail rotor.
2. Determine the bucket overall length from the following chart:
Lengths are accurate to within 1%. Specifications subject to change.
If a firesock is used,
add 8” (0.20m) to the above dimensions.
To confirm the bucket overall length, stretch out the bucket on the ground, pulling the
suspension cables taut. Measure the distance from the shackle on the head to the bottom of
the extended dump valve. If a firesock is attached, measure to the bottom of the firesock.
3. The tail rotor clearance is equal to the tail rotor length minus the bucket overall length.
4.
The tail rotor clearance must be a minimum of 6” (0.15 m).
NOTICE
If using a longline, the minimum recommended length is 50 ft (15 m).
