Type Certificate No. 4A30 issued December 15, 1961, Model 30. Application for Type Certificate dated July 21, 1958, Model 30. Type Certificate No. 4A30 revised October 10, 1962, to include Model 30A. Application for Amended Type Certificate for Model 30A dated March 21, 1962. Compliance with the following optional requirements has been established: Ditching Provisions only 4b.361 Ice Protection Provisions 4b.640 Production basis Model 30 and 30A, Production Certificate No. 605 Required equipment The basic required equipment as prescribed in the applicable airworthiness regulations (see Certification Basis) must be installed in the aircraft for certification. Convair Report ZM-30-069, "Master Equipment List, Models 30 and 30A," contains a list of all required equipment that must be installed as well as optional equipment installations approved by FAA. Service information Convair Report CS-61-053, "Convair Models 30 and 30A Structural Repair Manual" is FAA Approved. Service Bulletins and other service information, when FAA approved, will carry a statement to that effect. NOTE 1. (a) Current weight and balance report, including list of equipment included in certificated empty weight, and loading instructions, must be provided for each aircraft at the time of original certification. Convair Report ZW-30-029-, "Weight and Balance Report," for Airplane No. ", is applicable to both the Model 30 and 30A as indicated therein. (b) The airplane must be loaded so that the C.G. is within the specified limits at all times, with the effects of fuel use, gear retraction and crew and passenger movement being considered. See "C.G. Range" for 4A30 7 restrictions on center of gravity limits for takeoff at gross weights below 155,000 lb. (c) The weight of system fuel and oil as defined below and hydraulic fluid, all of which must be included in the airplane empty weight, is listed in Convair Report ZM-30-069, "Master Equipment List, Models 30 and 30A." System Fuel: The weight of all fuel required to fill all lines and tanks up to the zero fuel point on the fuel gages in the most critical flight altitude. This includes the unusable tank fuel as defined by CAR 4b.416. System Oil Including Usable: The weight of oil remaining in the engine, constant speed drive, thrust reverser, tanks and lines after subtracting the usable and reverser reserve oil from the total capacity. These values are noted under "Oil Capacity" and must be added to the empty weight of the airplane. (d) The "unusable" fuel, including drainable and undrainable quantities, is the amount of fuel in the tanks which is unavailable to the engines under critical flight conditions as defined by CAR 4b.416 and may be obtained by taking the difference between "total refuel" and "usable" tank capacities shown under "Fuel Capacity." This "unusable" fuel is included in System Fuel as indicated in 1(c) above. (e) Fuel loading and usable procedures are dictated by structural design and to maintain airplane C.G. within approved limits. Refer to Convair Report ZW-30-029-, the airplane weight and balance report for the Model 30 and 30A for loading, takeoff and landing fuel distribution limitations. (f) Fuel Jettison: Fuel jettisoning must be available for operation of the airplane in excess of the maximum landing weight. Refer to FAA Approved Airplane Flight Manual for limitations to be observed during fuel jettison operation. The unjettisonable fuel must be included in the airplane landing weight and the amount of usable fuel remaining in the tanks after complete jettisoning is as follows: Model 30 All Versions Model 30A Model 30A -6 & -8 -5 Version Versions Outboard tanks (1 and 4) 2452 lb. ea. 2462 lb. ea. Inboard tanks (2 and 3) 2600 lb. ea. *2786 lb. ea. *Applicable to Model 30A-5 Version when modified in accordance with Model 30 Service Bulletin 990 S.B. No. 28-12. Fuel weights are based on 6.7 lb./gal. NOTE 2. Reserved. NOTE 3. All replacement seats (crew, passenger and lounge), although they may comply with TSO-C39, must also be demonstrated to comply with CAR 4b.358(c). Other installations, such as berths, buffets, compartments or items of mass which could create a hazard to the safety of passengers and crew must also be demonstrated to meet the same requirements. NOTE 4. The 30-5, 30-6, 30-8, 30A-5, 30A-6, 30A-6AASC, and 30A-8 are versions of the basic Model 30 and 30A, respectively, the certification basis for which is Type Certificate No. 4A30. These dash numbers were selected by Convair primarily for contractual and clerical purposes and should not be considered to define different models of airplanes. One version may be converted to another by incorporating pertinent required equipment and complete conformity with corresponding approved drawings. It should be noted that the identification plate in the cockpit identifies the specific airplane version and that different airplane flight manuals, primarily the result of different autopilot installations, air-conditioning system, and electrical system, are applicable. Accordingly, when converting from one version to another, the identification plate must be suitably revised. The airplane flight manual pertinent to the new version must also be installed. Model 30 airplanes may be modified to like versions of Model 30A airplanes in accordance with Addendum I to General Dynamics/Convair Report ZM-30-070, dated September 28, 1962, "FAA Certification Drawing Index. When Model 30 airplanes are modified to model 30A airplanes, the "Nameplate" must be revised to indicate Model 30A, and the date of modification must be shown. 4A30 8 NOTE 5. Air Turbine Starter Ground Carts. Limitations on the use of ground bleed air sources used for starting the CJ805-23 series engines have been established and are noted under the recommendation section on Page 9 of Convair Report ZK-30-004. "Failure Analysis of the Model 30 Engine Starting System." NOTE 6. The engine thrust reverser lubrication and servicing must be accomplished per the schedule shown in Chapter 78 of the CJ805-23 series Aft Fan Engine Maintenance Manual, GEI 67837. NOTE 7. Applicable to the Model 30 and 30A Airplanes. (a) Installation of the CJ805-23 "k" and "o" Specification engines on the same airplane is permitted.
