Equipment The basic required equipment as prescribed in the applicable airworthiness regulations (see Certification Basis) must be installed in the aircraft for certification. In addition, the aircraft may incorporate such military equipment (except armament) as was originally incorporated in this type of military service. Additional equipment may be installed as can be substantiated on the basis that it presents no obvious hazard to safety. 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 Operations Limitations. 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. Notes Note 1. – A current weight and balance report including list of equipment included in the certificated empty weight and loading instructions when necessary must be provided for each aircraft at the time of original certification. 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 Aviation 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: “Do not lower landing gear above 175 mph.” “Do not lower flaps above 140 mph.” “Do not execute snap rolls above 140 mph.” “Do not execute slow rolls above 285 mph.” “Aerobatics prohibited: inverted flight, intentional spins, outside loops.” 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 the Army Technical Order No. AN-01- 25CN-1 except for limitations specifically called out in Type Certificate Data Sheet LTC-18 in which the values given in the specification must be observed.

The FAA does not have these documents available for distribution. Note 4. – 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 military aircraft are not required by the regulations and therefore are not available in the FAA Note 5. – For certification of night flyi ng, the following must be accomplished: Prior to obtaining certification for “Night Flying” the airplane must be equipped with type certification position lights, installed in compliance with the requirements of CAR, Parts 15.2 and 03.538.

Individual wing tip and tail switches with dim and bright positions and dimming resistors, if presently installed, shall be removed. With the exception of the landing lights, any other exterior lights are not required and may be removed or made inoperative, if so desired.
