REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

Service Bulletin A320-28-1138 (Mod. Nos 27496J1886 /38723J2944) was issued in 2005 after the

reporting of several in-service occurrences of wear and detachment of the top-stops from the Magnetic

Fuel Level Indicators (MFLI’s). These were found during fuel tank maintenance and on MFLI’s returned

to the Vendor, FR-HiTemp (now EATON AEROSPACE). Investigation has shown that the affected

MFLI’s were all of the early metal type (pre-mod 27496J1886) where the top-stop is retained with Sshaped lock-wire. Wear to top-stop retaining S-shaped lock-wire was found to be caused by repetitive

impact with the float, resulting in the complete detachment of the top-stop.

This raised concerns that a detached top-stop could come into contact or close proximity with a probe,

compromising the air gap between probe and the structure and creating a potential ignition risk in the

event of a lightning strike.

There are three different types of MFLI’s which could be installed due to interchangeability (ICY)

condition and each type has a different method of retaining the top-stop, these are:

- an early metal type of the series Part Number (PN) 3508802-XX series, where the top-stop is

retained with S-shaped lock-wire

- a later type of the metal type of the series PN 3508802-XX series, where the top-stop is retained

with a trapped wire

- a composite material type of the series PN FRH05000-XX series. This was introduced by Mod. No.

27496J1886 where the top-stop is push fitted on to a moulded end retainer and the retainer is

adhesive-bonded to the outer tube.

The modification Service Bulletin (SB) A320-28-1138 directed that any MFLI of the S-shaped lock-wire

must be replaced within 6,500 Flight Hours (FH) of the Airworthiness Directive (AD) effectivity date with

a post mod. design and any detached end stops located and removed. The SB also gave instructions to

do a visual check of the internal bore of the MFLI’s using an endoscope or an equivalent device to

determine which type of MLFI was installed.

SERVICE BULLETIN

SUMMARY

The effectiveness of the inspection procedure (visual check) detailed in SB A320-28-1138 has been

brought into question following the discovery by two operators of MFLI types which should have been

removed by the SB.

An investigation was carried out and considered:

- Operator feedback

- SB retrofit records

- Vendor records

- Availibility of parts for airlines

- Questions from operators during embodiment of SB A320-32-1138 collated since 2005

- Maintenance records of other operators from the SB.

The conclusion of the investigation was that the Design Office (DO) could not prove that other operators

had not made the same mistake.

This Service Bulletin details an inspection of all MFLIs in the wing tanks on the A320 family aircraft. The

inspection involves getting access to the wing tanks and completing a special in-tank visual inspection

of the MFLIs. This inspection method is considered to be clearer and less prone to error than the

endoscope (boroscope) inspection detailed in SB A320-28-1138.

Any MFLIs with the top-stop retained by the S-shaped lock-wire must be replaced with the composite

material type of the PN FRH05000-XX series MFLI, or in some locations replaced with the later type of

the metal type of the PN 3508802-XX series, where the top-stop is retained with a trapped wire.

When a top-stop is found to be missing from any type of MFLI, a tank inspection is to be carried out to

locate the top-stop. Also when a top-stop is found to be missing from any type of MFLI, a check to

identify any damage which may have been caused due to the missing top-stop within the fuel system, is

to be carried out.

NOTE: Missing top-stops may be found on a composite material type of the PN FRH05000-XX

series MFLI. If a top-stop is found missing from a composite MFLI, refer to EATON

AEROSPACE Service Bulletin No. FRH050002-28-2.

Accomplishment of this Service Bulletin will make sure that no early metal type of the Part Number (PN)

3508802-XX series, where the top-stop is retained with S-shaped lock-wire, is installed in the wing

tanks.

C. REASON

(1) History

Service Bulletin A320-28-1138 (Mod. Nos 27496J1886 /38723J2944) was issued in 2005

after the reporting of several in-service occurrences of wear and detachment of the topstops from the Magnetic Fuel Level Indicators (MFLI’s). These were found during fuel

tank maintenance and on MFLI’s returned to the Vendor, FR-HiTemp (now EATON

AEROSPACE). Investigation has shown that the affected MFLI’s were all of the early

metal type (pre-mod 27496J1886) where the top-stop is retained with S-shaped lockwire. Wear to top-stop retaining S-shaped lock-wire was found to be caused by repetitive

impact with the float, resulting in the complete detachment of the top-stop.

This raised concerns that a detached top-stop could come into contact or close proximity

with a probe, compromising the air gap between probe and the structure and creating a

potential ignition risk in the event of a lightning strike.

There are three different types of MFLI’s which could be installed due to

interchangeability (ICY) condition and each type has a different method of retaining the

top-stop, these are:

- an early metal type of the series Part Number (PN) 3508802-XX series, where the

top-stop is retained with S-shaped lock-wire

- a later type of the metal type of the series PN 3508802-XX series, where the topstop is retained with a trapped wire

- a composite material type of the series PN FRH05000-XX series. This was

introduced by Mod. No. 27496J1886 where the top-stop is push fitted on to a

moulded end retainer and the retainer is adhesive-bonded to the outer tube.

The modification Service Bulletin (SB) A320-28-1138 directed that any MFLI of the Sshaped lock-wire must be replaced within 6,500 Flight Hours (FH) of the Airworthiness

Directive (AD) effectivity date with a post mod. design and any detached end stops

located and removed. The SB also gave instructions to do a visual check of the internal

bore of the MFLI’s using an endoscope or an equivalent device to determine which type

of MLFI was installed.

The effectiveness of the inspection procedure (visual check) detailed in SB

A320-28-1138 has been brought into question following the discovery by two operators

of MFLI types which should have been removed by the SB.

An investigation was carried out and considered:

- Operator feedback

- SB retrofit records

SERVICE BULLETIN

- Vendor records

- Availibility of parts for airlines

- Questions from operators during embodiment of SB A320-32-1138 collated since

2005

- Maintenance records of other operators from the SB.

The conclusion of the investigation was that the Design Office (DO) could not prove that

other operators had not made the same mistake.

(2) Objective/Action

This Service Bulletin details an inspection of all MFLIs in the wing tanks on the A320

family aircraft. The inspection involves getting access to the wing tanks and completing a

special in-tank visual inspection of the MFLIs. This inspection method is considered to

be clearer and less prone to error than the endoscope (boroscope) inspection detailed in

SB A320-28-1138.

Any MFLIs with the top-stop retained by the S-shaped lock-wire must be replaced with

the composite material type of the PN FRH05000-XX series MFLI, or in some locations

replaced with the later type of the metal type of the PN 3508802-XX series, where the

top-stop is retained with a trapped wire.

When a top-stop is found to be missing from any type of MFLI, a tank inspection is to be

carried out to locate the top-stop. Also when a top-stop is found to be missing from any

type of MFLI, a check to identify any damage which may have been caused due to the

missing top-stop within the fuel system, is to be carried out.

NOTE: Missing top-stops may be found on a composite material type of the

PN FRH05000-XX series MFLI. If a top-stop is found missing from a

composite MFLI, refer to EATON AEROSPACE Service Bulletin No.

FRH050002-28-2.

(3) Advantages

Accomplishment of this Service Bulletin will make sure that no early metal type of the

Part Number (PN) 3508802-XX series, where the top-stop is retained with S-shaped

lock-wire, is installed in the wing tanks.
