1. REASON FOR REVISION

The revision 01 of this AOT is issued to inform C-295 operators about the release of Airworthiness Directive (AD) 

295/AD/IN/002/14 Edic.1 issued by DGAM (Spanish Military Airworthiness Authority).

No additional work is required by this revision for aircrafts who have performed the inspections required in the 

revision 00 of the AOT-C295-27-0001.

2. REASON

Airbus Defence and Space has received a report of a C-295 operator concerning a mechanical disconnection that 

was located in the kinematic chain from the co-pilot pedal set to the rudder control bars located under the cockpit.

2.1 FACTS

C-295 aircraft includes the adjustment device P/N FE150-001 (AC650107) on each pedal set to permit the

regulation of the pedals for pilot and co-pilot, by mean of a gear drive operated by a hand cranked twin output drive 

box (see item 110 on IPC 27-21-01 Fig.01).

During a pre-flight check, co-pilot pedals were found not aligned in their neutral position when the gust lock lever 

was on locked position. Further observations revealed that the eye-end of the pedal adjustment device was 

disconnected from the actuator (see Figure 01). 

2.2 CONSEQUENCES

A disconnection in the pilot or co-pilot pedal adjustment device could lead to a loss of the rudder control on the 

affected side.

2.3 AIM

The aim of this AOT is to provide C-295 operators with the necessary instructions to perform a visual inspection of 

the pedals adjustment device in order to confirm the correct installation on both pedals for each pilot position and to

inform C-295 operators about the issuance of DGAM AD 295/AD/IN/002/14 (attached to this AOT). This AD 

requires to perform the same instructions and recommendations defined in this AOT.

3. SHORT TERM ACTION

3.1 PLANNING AND MANPOWER

3.1.1 ACCOMPLISHMENT TIMESCALE

Airbus Defence and Space recommends to perform the detailed visual inspection described within the following 

paragraph before the next flight from the date of receipt of this AOT.

3.1.2 MANPOWER

To perform the visual inspection described, two persons are required. The approximated time required to perform 

the detailed visual inspection is 30 minutes.

3.2 DESCRIPTION

Perform a visual inspection inside pedals set on pilot and co-pilot station in order to confirm their correct alignment 

and installation of the adjustment device.

3.2.1 ACCESS

To get access to the inspection area, make sure that the pedals box area is free the obstacles. The pedal adjustment 

mechanism can be inspected through the lateral openings located in the pedals box.

3.2.2 INSPECTION REQUIREMENTS

NOTE: The following visual inspections must be performed on each pedal for pilot and co-pilot side.

3.2.2.1 Inspection of the pedals adjustment device union status

a) Adjust the pedals position to the correct length using the hand cranked.

b) Put the gust lock lever in its locked position.

c) Check through the lateral openings of the pedals box the correct installation of the union between the 

eye-end and the actuator of the adjustment device.

- Check that the nut AN316C6R, the plate locking FE154-000-16 and the washer tab FE154-000-09 

are correctly joined in accordance with the Figure 02.

- Check that washer tab FE154-000-09 is correctly bent, over the nut on one side, and over the axle in 

the other side (see Figure 02), in order to avoid the rotation of the axle.

3.2.2.2 Inspection of the pedals adjustment device union when the pedals are actuated (2 persons required)

a) Adjust the pedals to the most rearward position using the hand cranked.

b) Put the gust lock lever in its locked position.

c) Move the pedals while checking through the lateral openings of the pedals box that the union of the 

adjustment device and the actuator do not move independently but jointly.

d) Check that the eye-end does not have an independent movement relative to the actuator.

e) Repeat the previous steps with the pedals on the most possible forward position.

3.2.2.3 Inspection of the pedals adjustment device union when the hand cranked is actuated (2 persons required)

a) Put the gust lock lever in its locked position.

b) Move the hand cranked to the rearward and forward position while checking through the lateral 

openings of the pedals box that the union of the adjustment device and the actuator do not move 

independently.

c) Check that the eye-end does not have an independent movement relative to the actuator.

3.2.3 FINDINGS

In the case that the union is found not correctly installed, please contact Airbus Defense and Space for further 

instructions.

3.3 SPARES AND TOOLING

To accomplish this AOT it is necessary to use the following tooling:

a) Torch

b) Mirror

4. FURTHER INFORMATION

4.1 FOLLOW-UP PLAN

Airbus Defence and Space has detected that the Technical Publications do not meet adequate instructions to avoid 

the rotation and possible disengagement of the union.

The amended instructions have been included on the AMM April 2015 revision.

4.2 IMPACTED DOCUMENTATION

The impacted documentation is the following:
