Airworthiness Directive · Amendment 39-15820 · Navigation
PILATUS AIRCRAFT LTD. Model PC-12/47E Airplanes
Superseded. A later AD replaced this one: AD 2009-08-10. Comply with the one in force.
This AD applies to Model PC-12/47E airplanes, manufacturer serial number (MSN) 545 and MSN 1001 and subsequent, certificated in any category.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, before further flight after the effective date of this AD, do the following:
(1) Insert the following information into the Limitations section of the POH: “Maximum bank angle during climb must not exceed 30 degrees.”
(2) Insert the following information into the Abnormal Procedures section of the POH: “When a discrepancy is observed between the PFD and the electronic standby instrument system (ESIS), the aircraft should be flown with flight director (FD) and auto pilot (AP) engaged until the error corrects itself. The ESIS should be used as the primary means of attitude reference as long as the problem exists. If the problem does not disappear after 15 minutes, transition to visual meteorological conditions (VMC) conditions for the rest of the flight is required.”
(3) Insert the following information into the Normal Procedures section of the POH: “The FD shall be used for take-off in either heading or navigation mode as appropriate and with the heading or navigation properly set. The pilot shall include the ESIS in the normal scan.”
(4) Inserting a copy of this AD into the applicable section of the POH satisfies the requirements of this AD.
(5) The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations 14 CFR 43.7 may do the actions required in this AD. Make an entry in the aircraft records showing compliance with this portion of the AD following 14 CFR 43.9.
Note: This AD differs from the MCAI and/or service information as follows: (1) We changed the language of the information to be inserted into the Limitations section in order to make the required action legally enforceable. Specifically, we changed the word “should” to “must.” (2) We are not allowing incorporating Temporary Revision No. 9, dated January 30, 2009, into the POH as an alternative method of compliance to the requirements of this AD because of the enforceability issued described above.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
