Inspection Procedures

TB 1--1520--237-20--239

Inspection Procedures.

a. Inspect the fairing assembly to determine the configuration of the part. There are two configurations

of the tail rotor fairing (part number 70104-11104-044), fiberglass lay-up and injection molded. The fiberglass

lay-up fairing has smooth sides while the injection molded fairing has two raised sections on each side.

b. If the fiberglass lay-up fairing is installed on all four tail rotor blades, the inspection is complete and

the red horizontal dash / / - / / entry will be cleared.

c. If an injection molded fairing is installed, inspect the fairing assembly for cracks. The typical crack

occurs in the area where the electrical connector mounting bracket attaches.

(1) If cracks are found, proceed to paragraph 9.a..

(2) If no cracks are found, proceed to paragraph 9.b..

Correction Procedures. .

a. If a cracked injection molded tail rotor fairing assembly is found -

(1) Clear the red horizontal dash / / - / / entry required IAW paragraph 1.a. of this TB.

(2) Enter a new red / / X / / status symbol on the DA Form 2408-13-1with the following statement:

"Tail Rotor Blade (enter the tail rotor blade serial number here) Fairing Assembly Cracked."

Replacement of the fairing will be required prior to the next flight IAW TM 1-1520-237-23-3, paragraph

5-5-17.1, or TM 1-1520-250-23-3, paragraph 5.25.1.

NOTE

The injection molded fairing can be used as a replacement part until a fiberglass part can be ac-

quired.

b. If an injection molded fairing is installed and no cracks are found -

(1) Clear the red horizontal dash / / - / / entry required IAW paragraph 1.a. of this TB.

(2) Enter a new red / / X / / status symbol on the DA Form 2408-13-1with the following statement:

"Replacement of the Fairing Assembly (enter the tail rotor blade serial number here), required IAW

UH-60-02-ASAM-01 (TB 1-1520-237-20-239)." A separate entry is required for each tail rotor blade which

has the injection molded fairing installed.

NOTE

Replacement of the fairing will be accomplished as soon as a fiberglass fairing can be obtained

through supply.

(3) For each injection molded fairing installed, install a Tie Wrap (MS3367-6-0, Boot Tie Wrap)

to secure the de-ice bracket to the tail rotor horn.

(4) At each 10 hour/14day PMS, conduct a recurring inspection of the fairing in the area where

the electrical connector mounting bracket attaches, for cracks, and the Tie Wrap, for wear and security.

NOTE

ULLS-A units will use a "800" inspection number for the 10 hour/14Day recurring tail rotor blade

fairing assembly inspection.
