SUBJECT: ATA 35 – CHEMICAL OXYGEN GENERATORS EARLY REPLACEMENT
AIRCRAFT TYPE: A318,A319,A320,A321
OUR REF.: A35N006-14 Rev 00 dated 10-DEC-2014.
1. AIRCRAFT AFFECTED
All A318, A319, A320, A321 equipped with 15 & 22 minutes chemical oxygen generators PN 117042-XX manufactured in 2000 and 2001 by B/E Aerospace.
Oxygen generators PN details:
117042-02 (15 min – 2 masks) 117042-03 (15 min – 3 masks) 117042-04 (15 min – 4 masks) 117042-22 (22 min – 2 masks) 117042-23 (22 min – 3 masks) 117042-24 (22 min – 4 masks)
2. REFERENCED DOCUMENTATION
B/E Aerospace SIL D1019-01 B/E Aerospace VSB 117042-35-001
2.1 APPENDIX
Appendix A: Generator activation template
2.2 REFERENCES
Ref 1: MPD task 352142-01-1 - Discard chemical oxygen generators Ref 2: AMM task 35-21-00-920-001-A - Discard oxygen generators Ref 3: AMM task 35-21-41 PB 401 - Container - emergency oxygen - removal/installation
3. REASON
This AOT is issued to inform the affected operators of identified and still under investigation premature ageing on chemical oxygen generator PN 117042-XX manufactured by B/E Aerospace. Some operators reported that some generators manufactured in 1999, 2000 and 2001 failed to activate. Given the number of failed units reported, all the generators dated 1999, 2000 and 2001 shall be removed from the field.
As required by MPD task “Ref 1”, the generators manufactured in 1999 must be discarded before end of 2014. Therefore, this population is considered as being already covered by existing MPD task and is not considered within this AOT.
The management of generators manufactured in 2000 and 2001 is described in § 3.3.

3.1 FACTS
The MPD task “Ref 1” requires the replacement of chemical oxygen generators every 15 years.
During this replacement, it is normally required to initiate the chemical reaction of the removed generators for proper disposal. B/E Aerospace SIL D1019-01 is the document which provides instructions for the activation and the disposal of a removed generator.
On each chemical oxygen generato r, there is an indicator which changes colo ur with heat, indicating that the reaction producing oxygen took place. Some operators reported that when they tried to activate generators manufactured in 1999, 2000 and 2001 after removal from the oxygen contain ers, some of them failed to activate. The affected generators PN are 117042 -XX (either 15 min or 22 min oxygen duration).
3.2 CONSEQUENCES
Chemical generators manufactured in 1999, 2000 and 2001 may fail to activate and may not deliver oxygen.
3.3 AIM
This AOT requires the replacement of all oxygen generators manufactured in 2000, in priority.
Airbus assume that these generators are installed on Aircraft delivered the same year or early 2001.
This AOT requires that the generators dated 2001 be replaced after generators dated 2000 are replaced. However, to limit operational disturbance, when inspecting an aircraft suspected to have generators dated 2000, it is requested to remove any generator dated 2001 that is found.
For information, the generator manufacturing date is written on the generator label and on the oxygen container test lever sticker.
Note: based on feedback on operators practices, spare parts manufactured in 2000 & 2001 may have only been fitted on aircraft manufactured in 1988 or before. Nevertheless, operators must ensure that any spare generator dated 2000 or 2001, potentially fitted on their fleet, is removed in the same time constraints as mentioned in paragraph 4.1.1.
- For 1 5 min generators (PN 117042-0X), replacement generators manufactured in Lübeck, Germany by B/E Aerospace will be delivered with a kit in order to adapt the generator inside the container. Instructions for this replacement are given in the AMM task “Ref 3” and in the B/E Aerospace VSB 117042-35-001.
- For 22 min generators (PN 117042 -2X), fully interchangeable container s manufactured in Lübeck, Germany by B/E Aerospace will be delivered. Alternatively, r eplacement generators manufactured in Lenexa, US can also be ordered. They will fit directly in the current containers and will not need any adaptation such as the 15 min ones. The 22 min genera tor PN remains the same. Instructions for this replacement are given in the AMM task “Ref 2 and 3”.
If an operator has generators PN 117042 -XX in stock, and manufactured after 2001, they may be used as well.

After the replacement, this AOT requires to activate all the removed generators (as per instructions on SIL D1019-01) and requires to record for each generator the PN, the date of manufacture, the lot code and whether or not the chemical reaction worked properly. The template to record the activation results is provided in the appendix A of this AOT. This feedback from the operators is necessary for supporting the on-going investigation, will allow to determine the extent of this issue and will help to define further continued airworthiness actions.
Please refer to paragraph “7. REPORTING” to submit your feedback.
4. SHORT TERM ACTION
4.1 PLANNING AND MANPOWER
4.1.1 ACCOMPLISHMENT TIMESCALE
Replacement of all oxygen generators PN 117042 -XX manufactured in 2000 must be done as far as possible in advance of the MPD requirements and in any case not later than Jun e 2015, whichever occurs first.
Replacement of all oxygen generators PN 117042 -XX manufactured in 2001 must be done as far as possible in advance of the MPD requirements and in any case not later than December 2015 whichever occurs first.
4.2 DESCRIPTION
For 15 min generators (PN 117042-0X), please refer to AMM task “Ref 3” and B/E Aerospace VSB 117042-35-001 providing instructions for disassembly, assembly and testing.
For 22 min generators (PN 117042-2X), please refer to the AMM task “Ref 2 and 3”.
If an ope rator has generators PN 117042 -XX in stock, and manufactured after 2001, they may be used as well.
This AOT is the subject of an AIRBUS monitored retrof it campaign, which will be detailed in a Retrofit Information Letter (RIL).

5. FURTHER INFORMATION
5.1 FOLLOW-UP PLAN
Airbus have currently not received any failure report on generators manufactured in 2002 and after.
However, in order to investigate further this potential premature ageing, a sampling test on generators manufactured in 2002 and 2003 will be performed. The results of this sampling will allow Airbus and B/E Aerospace to adjust the retrofit and the sampling actions on these units if necessary.
5.2 IMPACTED DOCUMENTATION
As explained in paragraph 3.3, the 15 min replacement generators will be delivered with a kit in order to adapt the new generator inside the container as described in VSB 117042-35-001. This adaptation will lead to a container PN change. The post-MOD container is two way interchangeable with the pre-MOD one. The IPC will be updated accordingly.
