Applicability: Model 206A, 206B, 206L, 206L-1, and 206L-3 helicopters, certificated in any category, with main rotor blades part numbers (P/N) 206-015-001-001, 206-015-001-103, 206-015-001-105, or 206-010-200-033 installed.

Compliance: Required before further flight, unless already accomplished.

To prevent failure and separation of the main rotor blades and subsequent loss of the helicopter, accomplish the following:

(a) Visually inspect the Model 206A and 206B main rotor blades and determine if one of the following S/N blades is installed: TAC-0089, TAC-0542, TAC-0607, TAC-0614, TAC-0624, TAC-1643, TAC-1749, TAC-1776, TAC-1831, TAC-1911, TAC-1922, TAC-2399, TAC-2768, TAC-5742, TKK-9794, TKK-9883, or TKK-9933. If any one of these main rotor blades is installed, remove and replace with a serviceable part prior to further flight.

(b) Visually inspect the Model 206L, 206L-1, and 206L-3 main rotor blades and determine if one of the following S/N blades is installed: T-92, T-245, T-417, TLY-0075, TLY- 0095, TLY-0764, TLY-0770, TLY-0973, TLY-1438, TLY-1619, TLY-1653, TLY-1697, TLY- 1766, TLY-1801, TLY-1858, TLY-1953, TLY-1984, TLY-2031, TLY-2039, TLY-2064, TLY- 2081, TLY-2148, TLY-2335, TLY-2337, TLY-2549, TLY-2603, TLY-2604, TLY-2625, TLY- 2633, TLY-2648, TLY-2745, TLY-2786, TLY-2951, or TLY-2954. If any one of these main rotor blades is installed, remove and replace with a serviceable part prior to further flight.

NOTE: The serial number may be found on the Bell Helicopter data plate located on top of the blade at the root end and is also marked on the root end of the lower grip plate in the 1.5 inch radius.

(c) If the serial number of the main rotor blade matches one listed in paragraph (a) or (b) of this AD, report the registration number and serial number of the affected helicopter and provide a copy of the parts tag with which the part was delivered, if available. This report is to be made to the Manager, Rotorcraft Certification Office, Southwest Region, Federal Aviation Administration, Fort Worth, Texas 76193-0170, telephone (817) 624-5170, within 10 days of the inspection. (Reporting approved by the Office of Management and Budget under OMB No. 2120-0056.)

(d) An alternate method of compliance which provides an equivalent level of safety, may be used if approved by the Manager, Rotorcraft Certification Office, Southwest Region, Federal Aviation Administration, Fort Worth, Texas 76193-0170, telephone (817) 624-5170.

This Priority Letter AD (89-22-01 R1) issued on November 21, 1989, revises Priority Letter AD 89-22-01, issued on October 18, 1989, and becomes effective immediately upon receipt.
