In addition, the aircraft may incorporate such military equipnent (except armament) as was originally incorporated in the type for military or naval equipment may be installel as can be substantiated on the basis that it presents no obvious hazard to safety. Weight and Balance Report including list of equipment included in weight must be submitted for each aircraft. or Navy weight records in current condition may be submitted in lied of an actual weight. The equipment list need include no more than the Required equipment as defined under "EQUIPMENT" above. items as may be reasonably considered removable and are such weight that their renoval or addition could noticeably affect the weight and balance of the aircraft. built into the aircraft structure need not be listed. ment list nust be prepared by the applicant for the approval of the certificating C.A.A. representative, and in such form that it can be atttached to the C.A.A. Operation Linitations. The following placards nust be prominently displayed in the positions In full view of all passengers: ¿This is a military type aircraft and under the Civil Air Regulations shall not be used for the carriage of passengers or cargo for compensation or hire." lettering shall be of a type which can be read easily from any seat in the cabin. ›. In the cockpit in ful. view ot the pilot: 'Do not extend wing flaps above 208 nph. "Do not extend landing gear above 160 nph." extend landing lights above 190 mph.i "De-icer boots operative - do not exceed 275 mph." "De-icer boots inoperative - do not exceed 325 mph¿"¿ "Close top engine cowl flap for take-off." NOTE 3. The following statenent must appear on the Operation Limitations: This airplane must be operated at all tines within the limitations set forth in Army Technical Order No. AN-01-70AJ-1 except for limitations specifically called out in aircraft specification AL-3 in which the values given in aircraft specification AL-3 must be observed. A copy of the pertinent Army Technical Orders and this specification nust be carried In all cases it will be the responsibility of the applicant to secure a copy of the correct Technical orders. The CAA does not have these documents available for distribution. All structural repairs should be made in accordance with Arny Technical Order No. AN-01-40AJ-3, also reference AN-01-401J-2 for maintenance. any repairs, or modifications (other than those covered in the pertinent Army or Navy repair manual) are made prior to or subsequent to NI certifi- cation, it is the responsibility of the owner to furnish sufficient evidence to a Civil Aeronautics Administration representative to show that the modified airplane maintains the same degree of airworthiness as the original. The C.A.A. can give no technical assistance on such matters since complete structural data for NI aircraft are not required by Part 9 and therefore are not available in the C.A.A. For certification for night flying the following nust be acconplishel: teplace the wing position liqhts with certificated units or satis- the lights if pertinent. Type A-9 wing position lights (AV-3033-5 through -8) nay be satisfactorily nodified by painting the inside of the frostel cover black. Type 4-9 (AN-3033-1 through -4) are satisfactory without modification. Replace the tail light with a certificated unit. conditions are providded for the position lights, either the resistors should be disconnected from the circuits and a single-pole-single-throw switch should be used to replace the two single-pole-double-throw switches presently installed for the wing-tip and tail lights, or the switches should be placarded to indicate that only the "bright condition" should be used. In either case the tail light and wing-tip lights should operate on one switch. War emergency engine ratings not elijible; therefore, anti-detonant injection equipment may be removed. If it is not removed, the water requlator lines and metered water transfer lines should be of the flexible on airplanes equipped with -27 engines, heat shields should be installed over all rubber type intake manifold pipe joint seals to prevent their burning from the radiant heat of adjacent exhaust pipes at the cylinder neads. The sleeve type rubber connections require an asbestos lined metal shield, AF stock Vo. 0235-83642 or eguivalent and a strap type 2-1/2 in. hose clamp. The late type metal intake pipe joints which have a rubber seal ring inside, require shield and clamp assembly, AP stock No. 0235-100 or equivalent. Douqlas Model A-26F and Model A-26C airplanes were redesignated while in military service as Model B-26B and Model B-26C airplanes, respectively. Some of the Model B-26C airplanes were further redesionated as Models TB-26C or 3B-26C when modified to incorporate certain military training or reconnaissance capabilities. Also, individual airplane nameplate may have been modified to signify United States Air Force instead of United States Army Air Force as the responsible military agency. reidentified in any of these respects is considered to be essentially identical to a Model A-26B or A-26C airplane; they are eligible for airworthiness certification under the provisions of this specification vith no change of nameplate. No original NL airvorthiness certificates may be issued after 8/31/48. list of madatory changes required prior to original certification may be obtained from CAA Aircraft Service, Washington 25, D.C.
