P-51B-1-NA serial number 43-12252 (see note 6) Certification basis CAR 09 effective November 21, 1946 (Limited Type Certificate No. 11 issued April 10, 1947) Production basis Production certificate 724NM. Productio n of parts allowed under this PC. Production of new aircraft not allowed. Export Eligibility New parts produced under PC 724NM ar e eligible for a Certificate of Airworthiness for export. Complete aircraft not eligible for a Certificate of Airworthiness for export. Equipment: No Equipment other than engines and propellers are specified. However, such equipment as required by Federal Regulations for the particular operation authorized for civil registered aircraft must be installed. Also, any additional equipment necessary for the proper operation of the aircraft must be installed. In addition, the aircraft may incorporate such military equipment (except armament) as was originally incorporated in the type for military or naval service. Additional equipment may be installed as can be substantiated on the basis that it presents no obvious hazard to safety. Note 1. – Weight and Balance Report including list of equipment included in the certificated empty weight must be submitted for each aircraft. Army or Navy weight records in current condition may be submitted in lieu of an actual weight. The equipment list need include no more than the following: (a) Required equipment as defined under “Equipment” above. (b) Additional items as may be reasonably considered removable and are so located or of such weight that their removal or addition could noticeably affect the weight and balance of the aircraft. Items built into the aircraft structure need not be listed. The equipment list must be prepared by the applicant for the approval of the certificating FAA representative, and in such form that it can be attached to the FAA Operating Limitations. Note 2. – The following placards must be prominently displayed in the position indicated: (a) In the cockpit full view of all passengers: “This is a military type aircraft and under the Federal Regulations shall not be used for the carriage of passengers or cargo for compensation or hire.” The placard and lettering shall be of type which can be read easily from any seat in the cabin. (b) In the cockpit in full view of the pilot: (1) A dive limits placard in accordance with, T.O. AN-01-60J-25 for all models. (2) “Do not extend full flaps above 165 mph.” (3) “Do not operate landing gear above 170 mph.” (c) The airspeed indicator shall be marked as follows: (1) A red radial line at 505 mph. (2) A green radial line at 325 mph. (3) A yellow arc (precautionary range) shall extend from the green radial line to the red radial line. Note 3. – The following statement must appear on the operations Limitations: “This airplane must be operated at all times within the limitations set forth in Army Technical Order No. AN-01-60JD- 1 for the P-51C, AN-01-60JE-1 for the P-51D (F-51D) and P-51K (F51-K), and T.O. 01-60-123, 01-60-126 and 01- 60J-26 for applicable models, except for limitations specifically called out in LTC-11 in which case the values given in LTC-11 must be observed. A copy of the applicable Army Technical Orders and LTC-11 must be carried during flight.” In all cases it will be the responsibility of the applicant to secure a copy of the correct Technical Orders. The FAA does not have these documents available for distribution. Note 4. – All structural repairs should be made in accordance with Army Technical Orders AN-01-60-3 for all models, or alternately use AN-01-60JD-3 for the P-51C and AN-01-60JE-3 for the P-51D and P-51K. If any repairs or modifications are made prior to or subsequent to airworthiness certification, it is the responsibility of the owner to furnish sufficient evidence to an FAA representative to show that the modified airplane maintains the same degree of airworthiness as the original. The FAA can give no technical assistance on such matters since complete structural data for surplus military aircraft LTC’s is not required by the regulations and is therefore not available in the FAA Note 5. – Prior to obtaining certification for night operation, the following modifications to the exterior lighting must be made in order to comply with the general requirements of the Civil Air Regulations. (a) Position Lights: (1) Wing tip – If Type A-7 or A-8 light assemblies are installed, they must be replaced with type certificated light assemblies. If Type A-9 (AN-3033-10 or AN-3033-5 through 8) light assemblies are installed, LTC-11 Page 4 of 9 they may be satisfactorily modified by painting the sand blasted portion of the inner surface of the AN- 1042-3 and -4 covers black. The AN-3033-9 or AN-3033-1 through -4 light assemblies are satisfactory without modification. (2) Tail – the Type D-1 (AN-3091-1 through -3) and the Type D-2 (AN-3092-1 through-3) light assemblies are unsatisfactory and must be replaced with type certificated units. (b) Position Light installation: The position lights shall be installed to comply with the requirements of the CAR, Parts 15.2 and 003.538. (c) Position Light circuit and control: The Position light (wing tips and tail) shall be controlled by one SPST switch,. The circuit should be protected by its own fuse or circuit breaker. The individual wing tip and tail light switches with dim and bright positions shall be removed and the dimming resistors presently installed shall be disconnected. (d) Other exterior lights: With the exception of the landing lights, any other exterior light are not required and may be removed if so desired. Note 6. - The P-51B-1 and P-51C-1 series of aircraft are identical in dimension and performance, having minor and insignificant differences in internal configuration. The noted P-51B-1 serial numbers are included based on a finding of identicality with the P-51C-1 model. All information on this TCDS for the P-51C model is applicable to the P-51B model Note 7. - The following Mandatory Technical and Service Change or ders pertinent to models and serial numbers as indicated are listed for your information and must be complied with prior to certification. The FAA does not have copies of these publications available for distribution. Also, FAA inspectors do not have such material. The applicable Technical Orders and compliance data are also listed in the airplane’s “Historical Records”, A.A.F forms 60A, 60B, and 61 accompanying the airplane. All serial number references to the P-51C and P-51K models also apply to the F-51C and F-51K models respectively. Refer to Technical Order for serial no’s if not indicated in the following table.
