Weight & Balance for Mooney M10 Cadet

aircraft models approved under EAA automotive gasoline STCs. This revision supersedes Service Bulletin 2000-1, dated March 1, 2000. Revision reflects change of ownership of STCs from EAA Aviation Foundation to Experimental Aircraft Association, Inc. and previous EAA Foundation consolidation of Autofuel STCs into two STCs specified as SA01944CH and SE01943CH. REASON: A new aviation fuel known as 82UL has been approved in the United States. Due to the possibility of 82 UL having a higher volatility than previous aviation fuels and because of other differences from previous aviation fuels, it has been determined that some method of airframe re-certification was needed. Since, among many other things, volatility testing was conducted as an integral part of automotive gasoline STC testing and 82UL has a lower volatility requirement than automotive gasoline, the FAA has approved the use of 82UL aviation gasoline in aircraft which hold an Automotive Gasoline STC. However, 82UL is not suitable for every airplane which utilizes an automotive gasoline STC. The octane of 82UL is more than adequate for use in engines that were originally rated on 80/87 or lower octane fuel. EAA STCs only cover engines that were certificated to 80/87 grade or lower gasoline. However, STCs issued for some higher compression engines require the use of 91 octane at a minimum. Airplanes so equipped are NOT ELIGIBLE for the use of 82UL. Installation of revised fuel placards is intended to clarify the minimum fuel octane requirement of each airplane modified to use automotive fuel and prevent the introduction of 82 UL into higher compression engines. COMPLIANCE: No later than August 1, 2000, replace previously installed fuel placards with revised fuel placards which specifically state: EAA Aviation Center PO Box 3086, Oshkosh, WI 54903-3086 Ph: 920.426.4800 Fx: 920.426.6560 www.eaa.org THIS AIRCRAFT IS APPROVED TO USE THE FOLLOWING UNLEADED GASOLINES: Automotive Gasoline 87 Min.

It is the owner/operators responsibility to ensure that the most recent revisions to the AFM Supplement or Field Information Bulletins are obtained and adhered to. The most recent revisions can be obtained by calling EAA at (920) 426-4843 or emailing stc@eaa.org. Basic Operation: Basic operation of the aircraft remains the same. See FAA Approved Flight Manual Supplement. Airworthiness Limitations: Remains the same. Maintenance: Keep fuel tanks full whenever possible. Water condenses on the walls of partially filled tanks and enters the fuel system. Filter all fuel entering the tank. Drain fuel sumps regularly. Periodically inspect and clean all fuel strainers (screens) and occasionally flush the carburetor bowl as recommended by the aircraft manufacturer. The best insurance against fuel problems is to practice good housekeeping in your routine maintenance and be constantly alert. Inspection: Refer to FAA Approved Flight Manual Supplement, Section II - Procedures, (A)(1) Preflight Inspection. Troubleshooting: Remains the same. Revisions: Should a revision to this ICA become necessary, a letter will be submitted to the Chicago ACO with a copy of the revised ICA. Experimental Aircraft Association, Inc.

BOX 26460 OKLAHOMA CITY, OKLAHOMA 73125-0460 SAIB's are posted on the internet at http://av-info.faa.gov U.S. Department of Transportation Federal Aviat Administratic No. CE-00-19] April 5, 2000 This is issued for informational purposes only and any recommendation for corrective action is not mandatory. Introduction: The purpose of this Special Airworthiness Information Bulletin (SAIB) is to clarify text as noted below and alert registered owners/operators of airplanes FAA approved for the use of high-octane automobile gasoline (autogas). All other information provided remains the same. The FAA Small Airplane and Engine and Propeller Directorates have approved the use of 82UL gasoline (fuels meeting ASTM specification D6227) as an alternative to autogas (fuels meeting ASTM specifications D439 and D4814). Aviation 82UL gasoline has not been approved as an alternative to leaded grade 80/87 aviation gasoline. Aviation 82UL gasoline may not be used as a substitute fuel on airplanes requiring autogas with an aviation lean {motor method (MON)} octane rating greater than 82 or an antiknock index {(RON+MON)/2} greater than 87. Using this fuel on those higher performance engines originally approved for use with higher-octane fuels could result in engine detonation and associated destructive damage. Aviation 82UL gasoline is only approved for use in airplanes incorporating supplemental type certificates (STC) approving the use of autogas with an aviation lean octane rating of 82 or less or an antiknock index of 87 or less. The minimum octane requirement unique to any airplane (and engine) approved for autogas is placarded. Background: Numerous STCs and several airplane and engine type certificates (TCs) have been issued approving the use of unleaded autogas. Airplanes and engines approved for autogas use have met the FAA certification requirements for engine detonation, engine cooling, fuel flow, hot fuel testing, fuel system compatibility, vapor lock, and performance. Many of these approvals are for regular grade unleaded autogas in lieu of Grade 80/87 aviation gasoline. However, some of these approvals are for premium grade autogas in lieu of 91/96 or 100LL (100/130) aviation gasoline. Gasolines meeting the specification 82UL are intended for airplanes using lower-compression, lower-performance engines that were originally approved for use with Grade 80/87 aviation gasoline. Aviation 82UL gasoline is produced from autogas stocks, but is more tightly controlled and does not allow many of the additives. Use of this fuel on higher performance engines originally approved for use with higher-octane fuels could result in engine detonation and associated http://www.faa.gov/aircraft/safety/alerts/saib/media/CE-00-19R1.htm 4/26/2007 SAIB CE-00-19K1 Page 201 2 destructive damage. Therefore, 82UL gasoline may not be used as a substitute fuel for autogas approvals on airplanes that require fuels with an octane rating greater than 82, or an antiknock index greater than 87. Recommendation: The FAA highly recommends installing placards stating the use of 82UL is or is not approved on those airplanes that specify unleaded autogas as an approved fuel. Please contact the STC/TC holder directly for further information regarding the use of 82UL gasoline. A majority of FAA STC approvals for autogas have been issued to either the Experimental Aircraft Association (EAA) or Petersen Aviation, Inc. Placards and instructions may be obtained for those STC's as follows: EAA Service Bulletin: 2000-1 dated March 1, 2000 Petersen Bulletin: Aviation Service P-2000-1 dated February 15, 2000 For Further Information Contact: Scott Sedgwick, Aerospace Engineer; FAA Aircraft Certification Service, Small Airplane Directorate, 901 Locust Street, Rm 301, Kansas City, Missouri, 64106; telephone: (816) 329- 4132; facsimile: (816) 329-4090; email: scott.sedgwick@faa.gov http://www.faa.gov/aircraft/safety/alerts/saib/media/CE-00-19R1.htm 4/26/2007 US Department of Transportation Federal Aviation Administration Memorandui Subject: INFORMATION: Approval of Ethyl-Tertiary-Butyl- Ether (ETBE) Oxygenate Additive for use in Autogas Supplemental Type Certificates (STCs) From: Manager, Small Airplane Directorate, ACE-100 Manager, Engine and Propeller Directorate, ANE-100 To: See Distribution Date: DEC 1 1995 Reply to Attn. al: Alpiser (816) 426-6934 Methyl-Tertiary-Butyl-Ether (MTBE) oxygenate additive was approved for use in aircraft with autogas STCs on December 14, 1992. Advisory Circular (AC) 23.1521-1B was subsequently issued on March 2, 1995, permitting the use of MTBE additive. MTBE is used as a blending agent by the oil companies to increase the antiknock index of gasoline, and to meet Environmental Protection Agency (EPA) standards. Ethyl-Tertiary-Butyl-Ether (ETBE) oxygenate additive is also being used by the oil companies to increase the antiknock index of gasoline and to meet EPA standards. Research tests, conducted at the FAA Technical Center, with autogas blended with ETBE have not shown any safety related problems. Material compatibility and performance data supplied by the Experimental Aircraft Association and Petersen Aviation, the main holders of autogas STCs, also have not shown any safety related problems with autogas blended with ETBE. FAA service difficulty reports do not reveal any material compatibility or safety issues with ETBE additive. Accordingly, the FAA has determined that autogas blended with ETBE can be used safely in aircraft. Autogas blended with ETBE is approved for use in aircraft that are approved for the use of autogas by STCs. Michael Gallagher 10/23/45 Date Paidee Jay J. Pardee 11/2095 Date
