Wrench and Elbow Bending LogoSizes (S – 2XL)

This is a 3 day event which is intended to advance the delicate maintenance our aircraft require. As Ken will say, “This is about teaching how our planes need to be maintained, not free mechanical work!”  It is officially sponsored and hosted by Yankee Aviation, presenting interesting seminars as will a couple of other Grumman Savvy mechanics.  There will be hands on maintenance demos and plenty of opportunity for questions and answers during, and following, the sessions.

Rental Cars:
Enterprise 513-737-4100 ($45/day)

What To Expect If Yours is a Demo Airplane
If your airplane is used for instruction purposes showing how to maintain or fix a problem, then you can expect to pay for any parts and material used in that process. The labor is donated by the gurus to educate others, and the hosting shop is donating the workspace and tools, so if you want to make a donation, make it to the hosting organization GPA.

There is plenty of aircraft parking on the ramp and there will be ample “on site” food prepared by Roscoe and other volunteers on Friday evening, Saturday lunch, and possibly Saturday evening so plan to “chip in” on the food (and beverage) runs made to local stores. (There will be a recommended amount announced.) We may have one meal at one of the nearby restaurants, possibly Saturday evening.

One of the lessons learned at the first Wrench and Elbow Bending Weekend was that any schedule is no good after the first plane. You find stuff not expected and so cover stuff out of schedule. So, like our planes, we will be winging it! We’ll try and get all the subject in in some order.

Expenses to cover:
This event is sponsored by Roscoe & Yankee Aviation and Ken Blackman of Air Mods NW
and there is no charge for the seminars and demonstrations. The food and supplies, provided, are
paid supplied by the host and it is requested all make a donation to “the Kitty” to reimburse him. Use your own judgment but an amount of around $10 each for lunches and perhaps $5 for coffee
and muffins seems appropriate. The meal(s) at hotels and restaurants will be paid direct to them.

There are at least two good hotels near the airport which are:

Holiday Inn Express Fairfield 3.4 miles
LaQuinta Inn Cincinnati North 4.8 miles
Mariott Courtyard Hamilton 4.7 miles Ask for Cincinnati Jet Center Discount ($90 / night)

Information will be posted on The Grumman Gang as well as here on the GPA website. Plans are still being made and soon will be more formal so watch for updates. For now, just put these dates on your calendar and make whatever plans needed to attend.

One thought on “Midwest Wrench and Elbow Bending Weekend

  1. I have just purchased a 50% share of N28289, ’77 Grumman Tiger and will be flying in to meet you all from Oklahoma. I have the seat track issue and wanted to ask if you’d like to use this aircraft for a demo, if not I’ll repair it before I depart but just thought it might make a good example for a training session.
