9-20 Trailering
CAUTION
Trailering the R66 is not normally recommended. Most trailers
large enough to accommodate the helicopter are designed for
much heavier loads; the trailer’s springs and shock absorbers
will not function properly when lightly-loaded. Also, without
support, the tailcone can resonate with trailer vibrations,
subjecting the tailcone to greatly amplified loads.
If trailering is unavoidable, observe the following precautions:
1. Load trailer with ballast to an average weight the trailer is designed to carry.
2. Support the tailcone. Cushion support point(s) to prevent tailcone damage.
3. Perform one of the following options:
a. Remove main rotor blades per Section 62-10. Pack blades in shipping crate. See R66
Illustrated Parts Catalog [IPC] Figure 99-11.
b. Install main rotor blade supports per Section 10-13.
c. Fabricate blade supports to unload droop stops. Position supports inboard of blade
extended tab. Cushion support points to prevent blade damage.
4. Restrain tail rotor to prevent teetering.
5. Fuel helicopter per Section 12-41.
6. Protect windshield, windows, rotor systems, and all fragile equipment from exposure to
highway debris and subsequent damage.
7. After trailering, perform 100-hour maintenance and inspection per Section 5-45.
