IR ‘Cessna Citation 500, 550, S550, 560 Series Aircraft Page 1.1 1.0 INTRODUCTION AND SYSTEM DESCRIPTION 1.1 Introduction LifePon, Inc. of Woodland, WA has developed a stretcher and patient loading system for use and installation in Cessna Citation 600, 550, $550, 560 Series aircraft. 1.2 System Description 1.2.1 Patient Loading Utility System (PLUS) ~ The PLUS is a structural module that mounts directly to the existing aircraft seat tracks with standard track fittings. The PLUS provides a latching station for the AeroSled, as well as housing the various medical systems. 4.2.2 AeroSled ~- There are two types of AeroSleds oligible on this installation: personnel and equipment. The personnel AeroSled is a structural tter that latches to the top of the PLUS and provides patient restraint and support. The equipment AeroSied is a similar iter that provides hard points on its top deck for the restraint of cargo and equipment. Use of equipment mounted con the equipment AeroSleds may require further Federal Aviation Administration (FAA) approvals. 4.2.8 Electrical System — An optional electrical system may be installed including a static inverter with 115 VAC or 230 VAC output, DC power plug, ighting, 12 VOC output, air pumps, and vacuum pumps. Electrical power for the PLUS is customer-furnished equipment. 1.2.4 Oxygen System ~ An optional oxygen system may be installed. This system includes one or more DOT-approved oxygen bottles with 2,215 PSI (15,272 KPa) maximum pressure, high- pressure regulator, distribution manifold, fill port, and outlets. Control of the system is provided by check valves in the outlets and a valve at the bottle outlet ‘Some systems include provisions for an optional European specification bottle. This bottle cannot be refilad while installed and must be removed for servicing.LifePor, Inc. Instructions for Continued Airworthiness for EGR-700-12 Woodland, WA U.S.A. PLUS/AeroSied Installation in the Rev. A ‘Cessna Citation 500, 550, $550, 560 Series Aircraft Page 2.1 2.0 INSTALLATION 21 Initial Installation {At the time of initial installation, and any time aircraft configuration changes affect these items, several safety and interior compliance checks must be performed. See the installation instructions below. ‘Atthe time of the intial installation, an FAA Form 337 (or its equivalent for non-US. registered aircraft) must be completed and sumitted by an appropriately rated individual or agency to the applicable airworthiness authorities (FAA), and maintenance record entries made per FAR 43.5 and 43.9. ‘At the time of the initial installation, FARs require that the aircraft weight and balance records, and ‘equipment list be updated to reflect the changes. The weight and balance computations should include adverse loading checks and be accomplished in accordance with AC43.13-1a Chapter 13, as well as the applicable aircraft manufacturer's service information. For the installation of a PLUS equipped with an electrical system, a ground EMI check must be performed in accordance with LifePort, Inc. drawing number 300-2209, "EMI Test Procedure." In addition, an electrical load check must be performed per AC43.13-1a Par 424, and applicable aircraft manufacturer's service information, ‘The required Flight Manual Supplement (FMS) must be inserted into the aircraft Fight Manual, Complete the first page of the FMS with the airplane model serial number and registration number. Complete the ‘weight and balance section with all sled locations and occupant arms. This is to give the pilot quick ‘20cess to the new occupant location, If subsequent modifications of the aircraft affect the PLUS installation, the above-listed items must be reviewed and revised as necessary. 2.2 — Subsequent installations ‘The following information apples to the PLUS only ~- the AeroSied is installed at the time of fight. Aiter the initial installation has been performed and signed off, additional removals and installations require only a log entry, and weight and balance change by a properly rated technician. if the aircraft is to be operated in more than one configuration (i.e. aeromedical and corporate or cargo. ‘tc.), this will facilitate changes from configuration-to-configuration by maintaining a weight and balance form for each configuration used.LitePor, Inc.

This LifePort, Inc, supplied information may be used in lieu of the following weighing procedure. Any subsequent modifications to the PLUS, or if this information is not available, will require that the PLUS be weighed again and its center-of-gravity position determined. ‘Only cettitied scales may be used for the weight and balance procedures. Position a certified scale with at least an 150-pound capacity under each end of the PLUS. The PLUS must be level for this purpose. See Figure 1. Record both scale readings as well as dimensions & and B. It will elp to insert a round bar between the PLUS and scale on each end to make reading dimensions A and B more accurate. ‘The AeroSied is not instalad on the PLUS for this procedure.

Position After PLUS Installation Either the entire aircraft must be weighed or the new weight and arm must be calculated from a ‘current weight and balance report, If the aircraft is to be weighed, see the applicable manufacturer's service information for procedures. If the calculations are to be performed, use the following procedure, The arm of the PLUS is the distance from the aircraft datum listed in applicable service information and T.C.D.S. added to the distance from the forward end of the PLUS to the PLUS CG. The weight and arm of the AeroSled is shown in table 2.1, Using the empty weight from a current weight and balance form, the new C.G. Is given by the following calculation: New Empty Weight = Previous Aircraft Empty Weight - Items Removed + Items Added Moment (For each item) = Weight of item X Distance from aircraft datum Total Moment = Sum of all moments. (Moments for items removed wil be negative) Total Moment New C.G. =Total Weight ‘The following is an example of a CG position calculation Using the PLUS example of section 8.4.1, an AeroSied Il P/N100-1002, a basic aircraft weight of 13000 Lbs at an arm of 201.9".

This inspection interval should not exceed 600 hours of operation. ‘Some AeroSled and PLUS systems are not always installed in the airplane. These systems must be maintained in accordance with the applicable FARs regardless.
