SECTION 8
MAINTENANCE AND REPAIR
8.1 Maintenance Requirements
(1) The maintenance-free design of the JetWave™ AES system does not require field
maintenance to maintain airworthiness.
(2) Maintenance of the JetWave™ AES system is limited to replacement of LRUs on verified
failure.
(3
) OAE do not require field maintenance, such as lu
brication of moving parts.
(4) If functional problems occur, the BITE can identify the fa
ulty JetWave™ AES LRU and the
Modman collates this information which can be accessed through the GUI provided. Refer to
BITE Philosophy on page 7-8 of this document for information on how to access the BITE
data.
If replacement of an LRU is deemed necessary, in consultation with the
c
ustomer's authorized JetWave
product support, It is strongly recommended that all repairs be performed only at the Honeywell
authorized facility.
Only qualified technical personnel, familiar with avionics systems, should perform the test procedures
provided in this document. Before performing any test or fault isolation procedures, read the safety
advisories.
• Remove the primary AC power delivered to th
e KANDU via
aircraft circuit breaker. This
will power down the KANDU, including the 38.5 VDC and the 24 VDC power supply to
the FMA or TMA.
• Wait 1 minute following the removal of power to KAN
DU before attempting cable
disconnect from FMA or TMA, or any physical contact with the FMA or TMA.
• Disconnect FMA or TMA Plug P1 and measure the voltag
e across Pin A and Pin B using
a voltmeter (38.5 VDC voltage line). The measurement should not exceed 1 VDC.
• Disconnect FMA or TMA Plug P3 and measure the voltag
e across Pin 5 and Pin 6 using
a voltmeter (24 VDC voltage line). The measurement should not exceed 1 VDC.
8.2 Continued Airworthiness, FAR 25.1529
The sections that follow supply instructions for continued airworthiness for the JetWave™ AES system.
The sections that follow are supplied in response to Federal Aviation Regulation 25.1529, Instructions for
Continued Airworthiness.
8.3 Airworthiness Limitations
(1) Installation of the JetWave™ AES OAE assembly and LRUs on an aircraft by supplemental
