INTRODUCTION
These Instructions for Continued Airworthiness (ICA) apply to Pilatus PC-12/45 and PC-12/47 aircraft that
have been modified in accordance with STC SA02266LA to remove Pratt & Whitney engine PT6A-67B
and replace with Pratt & Whitney engine PT6A-67P, and the addition of a Unison 300A generator,
associated air ducts specified in STC SA02266LA, and a modified Engine Information System (EIS)
The PT6A-67B engine utilizes a belt driven 28VDC generator outputting 149 amperes. The PT6A-67P
engine requires a gear driven generator due to casing differences between the -67B and the -67P
engines. A Unison Industries 28VDC 300 ampere generator was chosen and tested for this STC.
The PT6A-67P Engine allows operation at a higher ITT, which requires modification of the EIS to account
for the higher ITT limits. This modification is limited to look-up tables in software. In addition, a resistor
change inside the EIS allows for display of the secondary Unison Generator at higher amps.
Modification of an aircraft by this Supplemental Type Certificate obligates the aircraft operator to include
the maintenance information provided by this document, relevant to the aircraft into the operator’s
Maintenance Manual and the operator’s Aircraft Scheduled Maintenance Program.
1.1
REVISIONS
It may be necessary to issue revisions to this document. Revisions may add, delete and/or change data
as necessary. All revisions are by replacement of pages. Hand-written revisions are not acceptable.
Prior to being issued, all revisions will be submitted to the responsible FAA Aircraft Certification Office
(ACO) for review and will be forwarded to the appropriate FAA Aircraft Evaluation Group (AEG) for
acceptance. Upon acceptance by the AEG, the revision will be issued to each owner / operator whose
aircraft has been modified by this installation.
When issued, a Letter of Transmittal will be sent with each revision. The transmittal letter is the authority
to place the revision in this document. It gives instructions on how to put the revision into the manual and
includes a highlight column that gives a short description of the Reason for Change. It is recommended
that Transmittal letters be kept at the front of the manual for reference.
Each revision has a reference letter that starts at Revision A. A Record of Revisions page is given at the
front of the manual. When the revision has been placed into the manual, write the revision number and its
issue date on the Record of Revisions page.
Changes in this document are included by using red as an identifier.
1.2
DESCRIPTION AND OPERATION
The PT6A-67P engine is the same engine used by Pilatus on the PC-12E Model. The engine mounts,
truss, forward bulkhead, and supporting structure remain unchanged on the PC-12E model from the PC12/45 Model. With the updated EIS, differences between the engines performance parameters are now
included in this STC. Therefore, engine operating limitations are altered as noted in the PC-12/45, PC12/47 Airplane Flight Manual Supplement.
Page 8 of 13
Revision A, dated 2/18/12
The primary difference for this STC amendment is the inclusion of the modified EIS and an increase
secondary generator output to 300 amps. As noted, the PT6A-67B engine uses a belt driven 28VDC
generator outputting 149 amperes. The secondary generator on the PT6A-67P engine is gear driven and
this STC uses a Unison Industries with 28VDC 300 amps output, the same as for the PC-12/47E.
Cooling air to the 300A generator was insufficient with the existing ducting and air intake. This STC adds
an increased area NACA Duct to the Left Hand side of the engine cowling in the same area occupied by
the previous secondary generator cooling duct. It also adds a composite End Cap to the intake of the
generator and increases the intake air hose to 2.5 inches diameter, which is identical to the air intake hose
of the primary starter/generator. Flight tests determined that the modified NACA duct on the left side
cowling provides sufficient airflow to meet the Unison 300 amp generator cooling requirements.

INSPECTION REQUIREMENTS AND OVERHAUL SCHEDULE
2.1
INITIAL INSPECTION REQUIREMENTS
At initial PT6A-67P engine installation, ensure that the engine removal/installation has been documented
in the Maintenance Log Book in accordance with Pilatus Maintenance Manual 71-00-01.
Ensure that the engine components have been swapped in accordance with Pilatus Maintenance Manual
71-00-02 and documented in the Maintenance Log Book.
Ensure electrical connectors swapped from engine to engine are cleaned in accordance with Pilatus
Maintenance Manual 71-00-03 and documented in the Maintenance Log Book.
Ensure that the propeller has been installed and balanced in accordance with Pilatus Maintenance Manual
61-00-00 and documented in the Maintenance Log Book.
Ensure that the engine adjustments have been documented and the twenty ground tests listed in the
Pilatus Maintenance Manual 71-00-00 had been completed and documented in the Maintenance Log
Book.
Ensure the cooling air ducting is attached at the intake of the secondary generator in accordance with FTA
MDL 0201-00100 Revision IR or later
2.2
SCHEDULED MAINTENANCE REQUIREMENTS
In conjunction with 14 CFR 91.411 and 91.413 Certifications, perform a visual check of the NACA Duct for
visible cracking or ply separation.
Inspect the air intake ducting to the generator to ensure proper air flow is reaching the generator intake.
As noted in Section 1.2, there are no structural differences between the PC-12/45 with the PT6A-67B
engine and the PC-12/47E with the PT6A-67P engine installations. In addition, there is no change in the
airspeed limits and load factor limits. Therefore, there is no need to identify any unique structural
inspections for this STC SA02266LA installation. Refer to Finnoff Aviation Products, Aircraft Maintenance
Manual Supplement, Doc. No. FTA-FIN-002025 for maintenance procedures & requirements.
