Summary
Applicability
BD-500-1A10, Aircraft 50010 thru 50018, 50020 thru 50061, and 50063 thru 50065
BD-500-1A11, Aircraft 55003 thru 55016 and 55018 thru 55172
Reason
It is possible that the Overhead Storage Compartment (OHSC) tie-rod assemblies were installed
without the threads of the clevis correctly engaged in the turnbuckle of one end of the tie
rod assemblies. This can have an unwanted effect on the integrity of the OHSCs during an
emergency landing.
Description
The aircraft is put in standard configuration for maintenance. Some ceiling panels are removed.
An inspection of the tie rod assembly of each OHSC is done. If necessary, the tie rod
assembly is disconnected from the structure, adjusted, and installed to the structure again.
Some ceiling panels are installed.

Reason
Problem and effect
It is possible that the OHSC tie-rod assemblies were installed without the threads of the clevis
correctly engaged in the turnbuckle of one end of the tie rod assemblies. This can have an
unwanted effect on the integrity of the OHSCs during an emergency landing.
Objective/Solution
This service bulletin gives the procedure to do an inspection, and if necessary, an adjustment
of the tie rod assemblies to make sure that the threads of the clevis are correctly engaged in
the turnbuckle. This will prevent an unwanted effect on the integrity of the OHSCs during an
emergency landing.
Description
The aircraft is put in standard configuration for maintenance. Some ceiling panels are removed.
An inspection of the tie rod assembly of each OHSC is done. If necessary, the tie rod
assembly is disconnected from the structure, adjusted, and installed to the structure again.
Some ceiling panels are installed.
Compliance

Procedure
1 General information
Note
This service bulletin is classified as Mandatory or expected to be Mandatory by
an Airworthiness Directive (AD). The Procedure section of the Accomplishment
Instructions is Required for Compliance (RC) and must be done to comply with
the AD. The Job set-up and Job close-up sections, with the exception of the
return-to-service tests, are recommended and can be deviated from, done as part
of other actions, or done with accepted methods different from those given in the
service bulletin, as long as the RC section can be done and the aircraft can be
put back into a serviceable condition.
2 Job set-up
Note
The steps in the Job set-up section of this service bulletin are recommended
steps. The steps give a recommendation to get access to the work area. This
recommendation is to give a safe work area and to minimize possible damage to
surrounding aircraft parts. Alternative steps can be used at the discretion of the
operator.

Note
This procedure is applicable to the left and the right sides. The procedure that
follows is written for the left side. The differences are given.
3.1 If it is not possible to complete all the instructions in this service bulletin
because of the configuration of the aircraft, speak with a CRC representative
at 1 866 A220 CRC (1-866-222-0272) or 1-450-476-7676 or e-mail at
a220crc@airbus.com for analysis and to get an approved disposition to complete
this service bulletin.
3.2 Between FR22 and FR26, do an inspection of the tie rod (1) of the forward
left Overhead Storage Compartment (OHSC) to make sure that the clevis is
sufficiently engaged in the turnbuckle as follows:
Refer to Fig. 1.
3.2.1 Put a pin with a diameter that is less than 0.062 in. (1.57 mm) in the
inspection hole of the tie rod (1).
3.2.1.1 If the pin does not go through the tie rod, the clevis is
engaged correctly.
3.2.1.2 If the pin goes through the tie rod, the clevis is engaged
incorrectly.
3.2.2 If the clevis is engaged incorrectly, do the steps that follow:
3.2.2.1 Measure and record the length of the tie rod (1).
3.2.2.2 Disengage the clip from the tie rod (1).
3.2.2.3 Pull the pin and disconnect the tie rod (1) from the fitting.
