    Press Release: September 1, 2022
    For Immediate Release
    General Aviation Modifications, Inc. (GAMI) is pleased to announce that we have received the FAA’s Approval of the expansion of our Supplemental Type Certificates on the use of our G100UL High Octane, Unleaded Avgas. The Approved Model List (AML) now covers every spark ignition piston engine and every airframe using a spark ignition piston engine(s) in the FAA’s Type Certificate database.
    GAMI has conducted testing and certification of the G100UL under the FAA’s Supplemental Type Certificate Certification Program with a high level of FAA oversight for the past 12+ years. George Braly, GAMI’s co-founder and Head of Engineering said “We’ve been told by the FAA that this is the most thoroughly tested and documented STC that has ever been done at the Wichita Aircraft Certification Office.”
    GAMI’s G100UL has many advantages over today’s 100LL.
    1. In addition to having “no lead (TEL)” the fuel has equivalent octane performance and can work in even the most demanding high compression ratio and turbocharged engines.
    2. The G100UL has no “organometallic additives” or “scavenging agents” and as such burns exceedingly clean similar to today’s unleaded auto fuels. This results in exceptionally clean combustion chambers, free of deposits and materially improving such maintenance headaches like frequent oil and spark plug changes required with today’s leaded fuel.
    3. It is fully “miscible” or “fungible” with 100LL in any proportion without loss of properties and approved as such in the wing of an airplane.
    4. Being petroleum based, the G100UL can be produced at a large number of refineries or specialty chemical production facilities improving the logistics of delivering this aviation gasoline through the existing infrastructure
    5. The G100UL has been tested for its material compatibility and found to be acceptable for use with a wide range of materials. No changes are required of the aircraft or engine other than the application of placards.
    6. Operationally, the G100UL is virtually identical to 100LL and actually has a bit more energy (BTUs/gal.) for increased range of the aircraft.
    Tim Roehl, President and Co-founder of GAMI said “It’s a great day for GA! Not only can we look forward to a lead free fuel future, the benefits of the G100UL will improve the maintainability and reliability of our engines, enhancing dispatchability and safety!

    Impromptu European meeting for 2022

    Hi Folks,

    This is your European RD with an important message:

    As sad as the cancellation of our annual European meeting was we stubborn European breed didn’t want to abstain a third time from meeting friends and agreed on an impromptu meeting instead.

    There will be no prior arrangements. No (official) gala dinner. No official bus tour. Nobody has to be afraid of getting the ‚most prestigious safety-award‘ - I think.

    Just meeting with friends in a really nice place. I might be talked into giving a guided walk in the beautiful landscape.

    When: 1-4.6.2022 (European notation)

    Where: EGJB, Guernsey, Channel islands (Hint: very, very cheap fuel - at least to European standards)

    As of today there are still plenty of hotels around available albeit it being a long holiday weekend so you better book quick.

    Bring your cameras. Did I mention it’s beautiful from the air and on the ground?

    If you need more info/help/assistance in planning (Over-water-trip!) just mail or call me.

    See you there

    Dear Friends,

    it is with real sadness that we’ll have to cancel this years convention - again.

    Please see Rafal’s mail below for details. This war surely is a real reason for cancelling.

    It is up to you if you’ll ask for the proposed refund or if you’d like to donate. Totally up to you, no peer pressure. Please let Rafal know your decision through the convention email:

    First two years of Covid - now this war.

    After trying real hard for three years now and not having received a single application during those three years for a convention proposal I am at a loss if and where we can host another European convention.

    My email about a month ago did not trigger a single response from the membership. Not a single one.

    If you feel like you could host next years event, please get in contact with me.

    Thank you and safe flying to all,


    European RD of GOPA



    Hi Yogi,

    I regret to inform you that we will have to cancel the GOPA 2022 event in Krakow due to the situation in Poland, which due to the war in Ukraine is already difficult and is getting worse.

    2.7 million refugees have arrived here, and this number is growing every day, there is a shortage of various goods in shops and we all have additional responsibilities here. In addition, we observe an unprecedented increase in the prices of virtually all goods and services - from food to gasoline, and it certainly exceeds 15-20%. Moreover, we are observing major turbulence - many employees return to Ukraine, there are many bankruptcies and company failures.

    The money I received for the meeting via Wise, PayPal and bank transfer will be returned to senders with the proviso that some of them did not send 230 Euro but the equivalent in PLN converted at the time of sending. Currently, this exchange rate is significantly different to their disadvantage.

    Participants who have booked a hotel in Krakow are asked to contact the hotel directly in order to cancel the reservation.

     I think that Poland is not the best place for such meetings now, due to these circumstances, their existence was a force majeure.

     Best Regards, Rafał

    FAA Proposed AD re: delamination issues

    Great News:  Due to all the supportive submissions, which helped to document why the proposed AD was costly, largely unnecessary and would not contribute to the overall safety of the fleet, the FAA has just announced that they are not pursuing the AD that would require annual tap testing of the seams on all models of the Grumman Light Aircraft to determine if debonding issues were present. 

    During the comment period of the AD, GOPA took the lead in asking our Technical Director, John Cotter, to work up a submission detailing why this AD was unnecessary due to the fact that detailed descriptions of performing a tap test for delamination already existed in our Grumman maintenance manuals.

    Many, many thanks to John Cotter for his incredible detailed and accurate submission on behalf of the Grumman Owners & Pilots Association, thanks also to AOPA, Fortnight Aviation Maintenance, Fletchair and to all individual GOPA members and non-members who submitted documentation to the FAA as well.

    This is what your Grumman Owners and Pilots Association advocated for, and we are happy to see the FAA agrees.

    My very dear Grumman friends,

    as you have surely seen in the news there is an ongoing military conflict here in Europe. Totally unfounded and totally unwanted but direct influence is out of our hands. Very many countries are united in the fight against the initiating aggressor and are working towards some form of peace.

    The pressure within Russia is rising quite quickly. Thousands of  protesters are being jailed daily - numbers rising quickly. Being overly optimistic I am wishing for an end ASAP. Like most everybody else. 

    However, it could turn into a year-long conflict costing even more lives. 

    I surely don’t want to get into any politics but let me have one personal comment: Please bear in mind it is not ‚the Russians‘ who started it. It is one stubborn powerful person forcing it with his command line.

    There is much grief and pain within the families of the fallen on both sides.

    Sting once sang: ’I hope the Russians love their children too.’   Yes, they do. All the ordinary people want this to stop.

    This is a brief message to let you know that our event hasn’t been cancelled - yet. It might not help the Ukraine or Poland if we do not show up. I’ll get into more details later.

    Up to today Poland alone took on 1.2 million refugees from Ukraine. Other countries some as well but Poland bears 80% of the burden. It does cause them challenges - not only logistical ones.

    Rafal our polish friend and myself are in constant contact with the airfield, hotel etc. I have relations and contacts to Ukranian people and some background info constantly being updated. 

    So for the time being I’ll kindly ask you to be patient and stand by. Do not flood me nor Rafal with messages and requests.

    We are evaluating the situation regularly and a final decision will be taken later when we see more clearly. 

    We do appreciate your patience. Thank you very much.

    There are rumours or initiatives of participants letting the hotel have the rooms without a refund and not showing up.

    Please hold your breath for a while. This is a kind offer but is not the most effective solution to help the refugees.

    We fully understand if you want to cancel from your side or if you’d like to donate your hotel or event fee.

    Rest assured I will later beg you for money and donations anyhow. Whether you show up or not.

    Meanwhile please consider donating plentiful. We as pilots are quite well off while others left their loved ones behind and only have their clothes, maybe one or two children and grandma in tow and are in dire need for help and shelter.

    If the event will take place I have some preliminary plans how we could help the region and people while we’re there.

    Giving charity flights to children to distract them briefly and put a smile on their face being one of them. There’s quite a bit of logistic, etc involved but we’re not there yet.

    Once again - bear with us. We’ll keep you informed.

    Thank you for your understanding,

    Yogi, RD Europe

    The GOPA has formally made this submission to the FAA regarding our feelings on the recent NRPM on bond line inspections. Please have a look at our submission and it is suggested everyone also make a submission. You can use all or parts of the GOPA submission as you see fit. Thanks to John Cotter for leading this submission.
