upon receipt of this bulletin. For blades installed 

on a helicopter that have accumulated more than 

800 flight hours within the next 30 days or 50 

flight hours which ever comes first. 

PART II. Within the next 60 engine starts 

following accomplishment of Part I and every 60 

engine starts thereafter. This check is to be

more than 800 flight hours and repeated until the 

blade is removed from service or as instructed in 

Part III of this bulletin.
ASB 206L-09-159 

Page 4 of 20 

PART III. At the operator’s option. 

After review of the spar radiographs by Bell 

Helicopter, a letter will be provided indicating that 

the blade can remain in service with no further 

action required (terminating action to this 

bulletin) or, that the blade can remain in service 

provided that Part II of this bulletin is 

accomplished until retirement from service. 

DESCRIPTION: 

Bell's investigation of a Model 206L-1 accident last year (Information Letter 206L-08-

85) revealed that a main rotor blade fractured as a result of fatigue. The investigation 

established that a fatigue crack could occur if there was a combination of both residual 

stress in the spar and a larger than acceptable void in the adhesive applied between 

the blade's internal lead inertia weight and the spar, between blade stations 100 and 

145. If such a condition exists, a fatigue crack may be induced by the centrifugal force 

variation that occurs during the helicopter start/stop cycles. 

Main rotor blades affected by this bulletin may have the described combination of both 

residual stress in the spar and an adhesive void between the internal lead inertia 

weight and the blade spar. To be considered at risk of developing a crack, both

conditions have to be met. All blades listed in Table 1 may have residual stress in the 

spar. However, they may not have voids between the inertia weight and the spar. The 

presence of residual stress in the spar can not be verified by any means of inspection. 

However, an X-Ray inspection of the spar can identify if an unacceptable void exists 

between the inertia weight and the spar. If, after accomplishment of Part III of this 

bulletin, it is confirmed that no void exceeding the limitation is found, the blade is no 

longer considered at risk and no further accomplishment of Part II will be required. 

PART I of this Alert Service Bulletin provides instructions to identify main rotor blades 

that are affected. 

PART II of this Alert Service Bulletin introduces a recurring blade spar wipe check for 

a crack in all affected blades installed on a helicopter. 

 A 
ASB 206L-09-159 

Page 5 of 20 

PART III of this Alert Service Bulletin provides instructions to perform a one-time XRay inspection of all affected blades. This inspection consists of taking X-rays of the 

blade spar that will be sent to Bell Helicopter for review. After review, depending on 

the result, Bell Helicopter will issue a letter that contains one of the following 

statements: 

 The blade can remain in service with no further action required (terminating 

action to this bulletin). Or, 

 The blade can remain in service but Part II of this bulletin requires 

accomplishment until retirement from service. 

The Radiography must be taken by a Non-Destructive Inspection (NDI) Facility that 

has experience with accomplishing X-Ray for the aerospace industry. The NDI facility 

shall also be capable of performing the work described in Part III of the 

ACCOMPLISHMENT INSTRUCTION of this Alert Service Bulletin. Owners/operators 

can contact their local Bell Helicopter Customer Service Facility (CSF) or refer to the 

Bell Helicopter Customer Support and Service Directory to locate in the CSF network 

the closest facility with X-Ray capability, or Bell Helicopter approved main rotor blade 

repair facility. 

In addition, a list of Facilities with X-Ray capability can be found in Table 2 of this Alert 

Service Bulletin. This list is not all inclusive and is provided as a reference. The X-rays 

can be taken with either the blade installed or removed from the helicopter. 

APPROVAL: 

The engineering design aspects of this bulletin are Transport Canada Civil Aviation 

(TCCA) approved.

MANPOWER: 

Approximately 1.0 man-hour is required to complete PART I and PART II of this 

bulletin. 

Approximately 10.0 man-hours are required to complete PART III of this bulletin. 

Man-hours are based on hands-on time, and may vary with personnel and facilities

stock or installed on helicopter to determine if the blade is affected by this bulletin. 

-NOTEDecal P/N 31-080AD002026 can be ordered from Bell 

Helicopter. 

2. In order to provide a quick visual reference and identify the “blades affected” by 

this ASB, apply the “red stripe” decal (or paint if preferred) on both sides of the 

blade at the location indicated on the Figure 3. To prolong the life of the decal 

apply Edge sealer (C-349) on the decal. Replace missing or damaged decal or reapply paint as required. 

-NOTEThe marking of the spar at station 100 and 145 is required 

for accomplishment of Part II of this bulletin. For 

accomplishment of Part III b, the X-ray must be taken 

between stations 90 and 145 to ensure the complete section 

between stations 100 and 145 is captured. 

3. Mark the top surface of affected blades to identify blade station 100 and 145 as 

follows: 

a. The center of the blade bolt is blade station 18.5 (blade station zero being at the 

center of the mast). Use a permanent ink marker and make marks at blade 

stations 100 and 145. Refer to Figure 3.

Part II. Recurring wipe check. 

-NOTE- 

"Your National Airworthiness Authority (NAA) should be contacted to determine who 

can accomplish this main rotor blade wipe check, as it may be acceptable to be 

accomplished by a trained pilot or by trained maintenance personal depending on the 

regulatory requirements of your NAA." 

1. Gain access to main rotor blades upper surface. 

2. Using detergent (C-318 or equivalent), thoroughly clean the blade upper surface 

between blade stations 100 to 145. Allow enough time for the blade upper surface 

to dry. 

3. Check affected area (refer to Figure 3) for evidence of cracks as follows: 

a. Prepare blue food coloring solution that will be used to perform the check by 

thoroughly mixing the following in a clean container: 

 100 ml Isopropyl alcohol 99% (C-385) 

 100 ml clean tap water or distilled water 

 20 drops of blue food coloring 

b. Apply the blue food coloring solution in the area to be checked using 

cheesecloth (C-486) saturated with the solution or apply with a spray bottle. 

c. After 10 to 20 seconds, wipe off the solution with cheesecloth (C-486) in a 

spanwise direction. 

d. Carefully check affected area for evidence of a crack. If a crack is present, the 

blue food coloring solution will remain in the crack as the excess of solution is 

wiped off and/or the cheesecloth will catch on the rough edges of the crack. 

4. If a crack is found, remove the blade from service before further flight and contact 

Bell Helicopter Product Support Engineering. 

-NOTEThe following inspection must be accomplished by a mechanic 

5. If the blue food coloring solution wipe check as specified in step 3 above reveals a 

surface defect and the presence of a crack can not be confirmed, perform the 

following inspection:

1. Blade removed from helicopter. 

a. Secure the blade to a stable platform such as sawhorses or blade dollies. 

-NOTEThe marking of the spar at station 100 and 145 is required 

for accomplishment of Part II of this bulletin. For 

accomplishment of Part III b, the Radiography must be taken 

between stations 90 and 145 to ensure the complete section 

between stations 100 and 145 is captured. 

b. The blade shall be X-Rayed at the bondline in the radius of the mid-span 

weight, refer to Figures 1 and 2, from station 90 to station 145, refer to Figure 3. 

c. Blade stations can be located by placing a measuring tape at the center of the 

blade bolt hole. The center of the blade bolt is blade station 18.5 (blade station 

zero being at the center of the mast). The blade should have marks at stations 

100 and 145 previously made in Part I. Refer to Figure 3. 

d. Lead markers shall be placed on the blade to provide evidence of complete 

coverage and sufficient overlap. The film shall also contain lead numbers 

indicating blade P/N, S/N and station locations 90 and 145 as a minimum. 

e. Align the X-Ray beam perpendicular to the blade lower surface and center the 

beam 0.8 inch from the leading edge, refer to Figures 1 and 2. 

f. Process the films and return them to Bell Helicopter for review.
