BELL 206B · Model Guide
Overview
BELL 206B is a Bell 206-family helicopter. The family includes the 206, 206A, 206A-1, 206B and 206B-1. The supplied sources are not a flight manual. They cover two aftermarket items for the BELL 206B: Van Horn composite main rotor blades and a Kamatics KAflex rotor brake kit. No variant-specific performance or weight data is available.
- Registry data covers the whole 206 family (up to 6 passengers). This pack has no 206B-specific payload, weight or speed figures.
- Van Horn composite blades 20635000-501 are eligible for the 206B. Inspect at 300 hours and annually, with a deeper check at 2,400 hours.
- The KAflex rotor brake needs a KAflex driveshaft installed first under an STC. It is incompatible with BHT Service Instruction 206-30 or 206-63.
- The library record lists a piston engine but the registry family is turboshaft. Confirm the actual engine from the aircraft records.

Do the sources give BELL 206B performance and weights?
No. For the BELL 206B they contain only maintenance data for two aftermarket items. The registry gives family-level maxima only, such as up to 6 passengers, which are not BELL 206B figures.
Which BELL 206B blades do the sources cover?
Van Horn Aviation main rotor blade 20635000-501, which is eligible for the BELL 206B on helicopters modified per T.B. 206-91-133. Inspection is at 300 hours and annually, and again at 2,400 hours.
Can any BELL 206B take the KAflex rotor brake?
No. The BELL 206B must first have the KAflex driveshaft installed under STC. It also needs dual caliper rotor brakes per BHT Service Instruction 206-105. The kit is incompatible with BHT SI 206-30 and 206-63.
What should I check on the blades of a BELL 206B?
Check the abrasion strips and paint cracks, run a tap test for voids, and review the blade log cards. Look for any history of lightning, blade strike, overspeed or overtorque, which trigger specific inspections.

Van Horn composite main rotor blades
The blade is carbon/epoxy with stainless steel and nickel abrasion strips. The 300-hour and annual checks cover dents, cracks, blisters and trailing edge delamination. At 2,400 hours the grip plates come off for crack and tap-test checks. After hail, up to five voids of 1.0 inch diameter or less are acceptable on the upper surface. Sharp dents and punctures in the abrasion strips are not permitted.
KAflex rotor brake checks
Inspect the disk, cup and spacer. Twice a year, check that the disk is not thinner than .260 inch and its faces are parallel within .002 inch. The gap to the four caliper pucks should be consistent within .020 inch. Master cylinder output is set to 119 ± 8 psi. The retrofit is reported on FAA Form 337.
Records to ask for
Ask for each blade's historical record (log card), which records the blade weight. Ask for the KAflex Historical Service Record, Certificate of Conformance and Flight Manual Supplement. Confirm FAA Form 337 for the rotor brake and the blade track-and-balance history.
Summary written by AI from the source document. Check the original before relying on it. See which parts of Sprinkle are written by AI.
Safety notes
- Lightning strike: scrap the Van Horn blades and return them to Van Horn Aviation for testing.
- Main rotor overspeed above 114%: inspect the blades and check the attachment bushing for elongation over .0015 inch.
- Overtorque above 120 percent: inspect the blades at the time and again after 25 hours of operation.
