ISSUE 1: Select one of the following: compliance time 

If other, explain: 

Commenter(s): Mike Mattler 

What change to the AD action is requested? The periodical inspection for the EC 145 has moved from 

600hrs. to 800hrs. The periodical inspection for the EC 13 5 has moved from 800hrs. to I OOOhrs. Airbus 

Helicopter Inc. would like the revised AD to reflect these changes. 

Also In the current EC135 & EC145 ASB's it allows for the rebonding of the loose bearings. 

With this in mind Airbus Helicopter Inc. would like to propose changing the wording to drop the 

reference to the hourly 600/800 and revise the wording and the following changes to say; 

F.(l) For Model EC135 Pl, P2, P2+, Tl , T2, and T2+ helicopters: 

(E) At intervals not to exceed the Periodical Inspection/1 000 hours TIS or 36 months plus allowed 10% 

margin, whichever occurs first, inspect the bearings in the LH guidance unit, RH guidance unit, cyclic 

control, upper guidance unit, and linear voltage differential transducer plate for play. If any bearing is 

loose, replace lever or rebond the affected bearing II A/W AMM 20-00-00 2-14. 

F.(2) For Model MBB-BK 117 C-2 helicopters: 

(E) At intervals not to exceed Periodical Inspection/800 TIS or 24 months plus allowed I 0% margin, 

whichever occurs first, inspect the bearings in the RH guidance unit, LH guidance unit, and lateral control 

guidance unit for play. If any bearing is loose, replace lever or rebond the affected bearing II A/W AMM 

20-00-00 2-23.

EASAAD

IfPARTIALLY AGREE, we agree with We partially agree with the 10% margin. We will add the 

margin to the compliance time in hours TIS, but we cannot add a 10% allowance. We disagree 

with the updated inspection intervals because they have not been approved by EASA. We will wait 

Page 1 of3 
for the EASA AD revision because they are waiting for Airbus to clarify the ASB. We might 

consider further rulemaking if EASA approves the new inspection intervals. Make the following 

changes to the AD: Change 600 to 660 hours TIS and change 800 to 880 hours TIS. 

If NO, we don't agree because
