Type Acceptance Report TAR 10/21B/23 – Cessna 501-551

(1) ICAO Type certificate: FAA Type Certificate Number A27CE FAA Type Certificate Data Sheet no. A27CE at Rev. 18 dated July 29, 2015 – Model 501 approved January 7, 1977 – Model 551 approved June 30, 1978 (2) Airworthiness design requirements: (i) Airworthiness Design Standards: The certification basis of the Model 501 is FAR Part 23 effective February 1, 1965, as amended by Amendments 23-1 through 23-16, plus some paragraphs at a later Amendment status and some paragraphs from FAR Part 25 at Amendment 25-17, as detailed on the TCDS. For the Model 551 there were additional changes to individual paragraphs, again as detailed on the TCDS. One special condition was applied to the 501 and twelve equivalent level of safety findings granted for both. These have been reviewed and accepted by the CAA. This is an acceptable certification basis in accordance with NZCAR Part 21B paragraph §21.41 and Advisory Circular 21-1, because FAR 23 is the basic standard for Normal Category Airplanes called up under Part 21 Appendix C. There are no non-compliances and no additional special conditions have been prescribed by the Director under §21.23. (ii) Special Conditions: Model 501: 25-25-CE-4 – The FAA originally imposed additional requirements on the Model 500 because as a small jet airplane with MCTOW of 10,350 lb. it had characteristics which were novel or unusual for the Transport Category. It included certification standards for operation without normal electrical power; increased limit load factor; turbulence criteria; vibration and buffeting; and propulsion aspects (including installation fault analysis and precautions against rotor failure or engine case burn through). This Special Condition was carried across to the Model 501. (iii) Equivalent Level of Safety Findings: FAR §23.903(e)(2) Engine Rotation – Compliance was by showing that continued rotation at windmilling speed after engine shut down would not jeopardise the safety of the aircraft. FAR §23.951(c) Fuel System Icing – An ELOS was granted based on the required use of a Fuel System Icing Inhibitor MIL-I-27686, as specified in the Airplane Flight Manual (AFM). Type Acceptance Report Rev.1 : 30 October 2020 TAR 10/21B/23 – Cessna 501-551 5 FAR §23.995(f) Fuel System Check Valves – The FAA accepted that the intent of this requirement is met by the system design, whereby incorrect assembly or connection of the check valves would result in an annunciator panel indication following engine start. FAR §23.1019(a)(3) Oil Strainer Indicator – It was accepted that a bypass valve operation indicator is not needed because PWC affirmed that filters on time expired engines and those removed due to bearing failures were never contaminated to the extent that filter bypass occurred. FAR §23.1439(b) Protective Breathing Equipment – This ELOS was continued over from the Model 500, based on compliance with the FAR 25 provision. (During testing for smoke detection and removal it was satisfactorily demonstrated that PBE is not required for crew members. FAR §23.1563(a) Maneuvering Speed Placard – The FAR Part 23 requirement for a single VA placard was accepted as impractical and instead information is presented in the AFM as a function of weight and altitude in a graphical form. Type rating should ensure pilot familiarity. Model 501 Only: FAR §23.471 thru 511 Ground Loads FAR §23.723 thru 727 Landing Gear FAR §23.729(e) Retracting Mechanism FAR §23.731 thru 735 Wheels, Tires and Brakes A determination of ELOS for the four sets of provisions above relating to landing gear requirements was made based on compliance with the equivalent FAR 25 paragraphs, including the fatigue criteria of FAR 25.573. The trouble-free service history of the Model 500 landing gear was also considered. FAR §23.1335 Flight Director Disconnect – An ELOS was made based on the isolation provided in the Model 501 installation by the separate power inputs and signal outputs from the Sperry VG-14 vertical gyro to the attitude indicators, autopilot and Flight Director computers. FAR §23.1545 Airspeed Indicator Markings – Use of IAS in lieu of CAS was accepted provided both types are in the AFM and placard values are consistent with ASI markings. Model 551 Only: FAR §23.207(c) Stall Warning – A margin less than 5 knots was accepted because there was always heavy buffet and the elevator control forces became heavy. Further, controllability was always good and Vmin usually occurred rather than an aerodynamic stall. The Model 550 has also been found safe under Part 25, which is identical to the Model 551 and requires the same type rating. FAR §23.773(b)(2) Use of Clear Vision Area of Windscreen – For the Citation family Cessna has demonstrated alternate compliance in lieu of an openable window (the Citation has a small openable cockpit window but it is not properly located for forward vision) considering rain, ice, hydraulic fluid, hail and bird impingement, through natural clearing resulting from the shape of the windscreen and the plexiglass surface and a bleed air rain removal system. FAR §23.807(d) Emergency Exit Ditching – An ELOS was granted for the use of a Type III exit in lieu of an overhead hatch, after analysis showed it would be above the water line in all loading situations and provided easier and quicker access to both sides of the aircraft. Type Acceptance Report TAR 10/21B/23 – Cessna 501-551 Rev.1 : 30 October 2020 6 FAR §23.1199(b) and (c) Fire Bottle Pressure Relief Valve – In lieu of relief lines which discharge outside the aircraft and have visual discharge indicators, the FAA accepted compensating factors that the extinguishing agent is non-corrosive; the valve is located so equipment or structure will not be damaged by impingement; the aft fuselage discharge area is completely separated from the pressurised cabin and sized and ventilated such that over- pressurisation cannot occur; and there is easy access to the container pressure gauges to check the valve charge status. FAR §23.1549(a) and (b) N2 Digital Indicator Markings – An ELOS was granted for the use of digital displays which give less effective trend and limit proximity indications on the grounds the engine has no defined cautionary range for N2, can temporarily exceed the maximum N2 safely up to 2% for 20 seconds, and the display changes from green to red when an exceedance occurs. (iv) Airworthiness Limitations: See the Maintenance Manual Chapter 4 Airworthiness Limitations. (3) Aircraft Noise and Engine Emission Standards: (i) Environmental Standard: The Model 501 Citation I has been certificated for fuel venting under SFAR 27, and for noise under FAR Part 36, including Amendments 36-1 through 36-5. (Stage 3), For the Model 551 these standards were updated to Amendments 36-6, and 27-3. (ii) Compliance Listing: Model 501: AFM Section IV Performance – Noise Characteristics – Takeoff weight 11,850 lb. Takeoff: 78.0 EPNdB Approach: 87.9 EPNdB Sideline: 86.2 EPNdB Model 551: AFM Section IV Performance – Noise Characteristics – Takeoff weight 12,500 lb. Takeoff: 80.1 EPNdB Approach: 86.7 EPNdB Sideline: 90.5 EPNdB (4) Certification Compliance Listing: Cessna Report No. 501-7733-019 – Model 501 Master Compliance Check List Cessna Report No, 551-7833-093 – Model 551 Master Compliance Check List (5) Flight Manual: FAA-Approved Airplane Flight Manual for the Model 501 Cessna Citation I/SP – Document No. 501FM – CAA Accepted as AIR 3133 FAA-Approved Airplane Flight Manual for the Model 551 Cessna Citation II/SP – Document No. 551FM – CAA Accepted as AIR 3874 FAA-Approved Airplane Flight Manual for the Model 551 Cessna Citation II (Unit -550 thru -626) – Document No. 551FMA – CAA Accepted as AIR 3875 Type Acceptance Report Rev.1 : 30 October 2020 TAR 10/21B/23 – Cessna 501-551 7 (6) Operating Data for Aircraft: (i) Maintenance Manual: Apart from the AFM, all Model 500 Service Data is applicable to the Model 501, and all Model 550 Service Data is applicable to the Model 551.

A Design Rule reference in the Means of Compliance column indicates the Design Rule was directly equivalent to the CAR requirement, and compliance is achieved for the basic aircraft type design by certification against the original Design Rule. 2. The CAR Compliance Tables above were correct at the time of issue of the Type Acceptance Report. The Rules may have changed since that date and should be checked individually. 3. Some means of compliance above are specific to a particular model/configuration. Compliance with Part 91/119 operating requirements should be checked in each case, particularly oxygen system capacity and emergency equipment.
