SUPPLEMENTARY INFORMATION:
Discussion
On September 8, 2004, FAA issued AD 2004-23-01, Amendment 39-13856
[[Page 74413]]
(69 FR 64832, November 9, 2004), which applies to certain Pilatus
Aircraft Ltd. (Pilatus) Model PC-7 airplanes with any Lear Romec
RR53710B type or Lear Romec RR53710K fuel booster pump (Pilatus part
number 968.84.11.401; 968.84.11.403; or 968.84.11.404) installed.
This AD requires you to check the airplane logbook to determine
whether any installed fuel booster pump has been modified with spiral
wrap to protect the wire leads and has the suffix letter ``B'' added to
the serial number of the fuel booster pump identification plate.
If any installed fuel booster pump has not been modified, you are
required to inspect any installed fuel booster pump wire lead for
defects; if defects are found, replace the fuel booster pump with a
modified fuel booster pump with spiral wrap that protects the wire
leads; or if no defects are found, install spiral wrap to protect any
wire leads and add the suffix letter ``B'' to the serial number of the
fuel booster pump identification plate.
The pilot is allowed to do the logbook check. If the pilot can
positively determine that the fuel booster pump wire leads with spiral
wrap are installed following the service information and that the
suffix letter ``B'' is included in the serial number of the fuel
booster pump identification plate, no further action is required.
Need for the Correction
The FAA incorrectly referenced the amendment number as Amendment
39-13856. The correct amendment number is Amendment 39-13892. This
correction is needed to ensure that the amendment number is correct and
to eliminate misunderstanding in the field.

Amendment 39-13856; AD 2004-23-01, which was the subject of FR Doc. 04-
24717, is corrected as follows:
On page 64832, column 1, lines 18 and 19, replace Amendment 39-
