FLIGHT READINESS REVIEW & AFSRB NASA Goddard’s CAR (Cloud Absorption Radiometer)

1. FLIGHT READINESS REVIEW & AFSRB NASA Goddard’s CAR (Cloud Absorption Radiometer) Installation & Test Flights NASA/UARC Subcontract AA MSA 05-002 Tasks 1-3 PREPARED BY: SKY RESEARCH, INC. 01/31/2006

2. PROJECT DESCRIPTION • This FRR outlines the use of a Jetstream J31 twin-turboprop aircraft to carry the NASA Goddard Space Flight Center CAR (Cloud Absorption Radiometer). • The project is divided into three separate tasks under a UARC Subcontract with the University of California at Santa Cruz. • Tasks include: • Conceptual Design, Engineering and Analysis • Modifications, Fabrication and Installation • Evaluation Test Flight with FAA DER test pilot • A separate Task order will follow after completion of the DER Test Pilot’s evaluation of aircraft handling characteristics. This task will be to evaluate the CAR instrument during operational science flightson the J31.

6. CONCEPTUAL DESIGN, ENGINEERING & ANALYSIS • CAR Structural / Aero Integration • Forward Fuselage Modification • Structural Attachment • Rotating Fairing Design • Rotating Elements

7. AIRCRAFT • Jetstream 31, N22746: • Pressurized, twin-engine turbo prop aircraft, modified to provide an Airborne Sensor Platform for research, survey and reconnaissance missions • Large, wide cabin with standing headroom and oversized cargo pod for flexibility in deploying multiple sensors • A 10” NVG observation bubble window, dual SAT COM communication, dual GPS navigation, 8 position intercom, extensive inventory of aircraft spares and ground support equipment, survival equipment and extended range fuel tanks provide worldwide operations Jetstream 31

8. OPERATIONAL LIMITATIONS

9. SKY RESEARCH FACILITIES Aircraft modification, sensor installation, and maintenance activities are based at the Sky Research hanger at Ashland Airport (S03) located in Southern Oregon. Science test flights will be based out of S03 following installation of the CAR.

10. AIRCRAFT MODIFICATION • Aircraft modifications and maintenance: November through February, 2006 at the Sky Research facility in Ashland, Oregon • Engineering design for the CAR installation: completed in January, 2006 • CAR placement: former position of the weather radar system as engineered by Adaptive Aerospace. • Aircraft modifications: planned completion, 2nd week of February, 2006 Sky Research Facilities - Ashland, Oregon Modifications

11. EQUIPMENT INSTALLATION AATS-14 and SSFR installation modifications and placement of the sensors. CAR Testing the AATS-14 Mount Belly Mount and Top Mount of SSFR SSFR

15. INSTALLATION SUMMARY • Sky Research has been contracted to provide a platform in support of the installation of the CAR on their BAe Jetstream 31 aircraft. • Sky Research is responsible for the design, modification, and integration of the CAR instrument on the J31. • Validation science test flights are scheduled for February 15, 2006 in Ashland, Oregon • A flight test plan has been prepared by Terrance Donovan Ph.D. FAA DER certified test pilot. • Test flights address J31 safety with new configuration. • Test flights will be conducted during daylight hours under VFR conditions.

16. HAZARD ANALYSIS • The original Radome configuration has been changed and there will be a large slot cut in the newer, larger nose cone which is a major hazard consideration. It is impossible to predict all scenarios during this type of test flight; therefore, the possibility that D-1, or D2 on the risk Matix below may be encountered should be acknowledged. Risk Matrix, AR 385-16, MIL-STD-882C, ATTC MEMO 70-12 • Mitigating actions include: • FAA DER Test Pilot is qualified for this type of flight • Aircraft is equipped with stall protection systems (stick pusher) • The J31 is a multi-engine turboprop with single-engine capability • All scheduled and required maintenance is current

17. FAA DER TEST FLIGHTS • Typical ATC communications will be used during the taxi, takeoff and climb out phase of the test flights in Ashland, Oregon. The pilot will be in contact with the ATC and receive VFR traffic advisories during flight. • Ashland: CTAF/UNICOM: 122.8 • Seattle Center: 124.85 • Cascade Approach: 124.30 • Medford and Montague airports are close to Ashland in proximity, and have adequate runway lengths in the event an alternate is needed.

18. AIRCRAFT READINESS Aircraft airworthiness will be completed after a full review by Mr. J.D. Jordan, FAA Designated Aviation Representative (DAR) and in compliance with the Federal Aviation Administration. The J31 will be operated under an Experimental category Airworthiness Certificate issued for a full year beginning February 1st, that will cover operations in the continental U.S., Mexico and the Caribbean. SYSTEM INTEGRATION STATUS Instrumentation systems integration status checks will be completed in conjunction with the NASA-Ames test flights in mid-February. Instrument calibration test flights are scheduled, with allotted time for additional flights if necessary prior to Milagro deployment. ACCEPTANCE TEST RESULTS Final FAA acceptance tests will be completed after NASA approval and before operational test flights at Ames.
