Welcome to EAA Chapter 105
Experimental Aircraft Association (EAA) Chapter 105, which was incorporated in 1961, is located in the Portland, Oregon area and is headquartered at Twin Oaks Airpark. We have more than 200 members and can say with pride that we are one of the most active and passionate EAA chapters in the country. Our history is rich with aviation innovators and doers, and we continue with that tradition today. We invite you to come to check us out, join our organization, visit us for our monthly pancake breakfast, and participate in the adventure and sheer joy of aviation!

The Early Days
Although the EAA hasn’t maintained its earliest records, the chapter was apparently chartered in 1961. The earliest chapter status report is dated 12/31/65 at which time Dick “Van” VanGrunsven was president. At that time there were 88 members with 50 home-built aircraft under construction, 11 flying home-built aircraft, and 1 vintage aircraft under restoration. The chapter was formally incorporated on January 26, 1966.
During those early years, chapter members didn’t have a cushy (relatively speaking) chapter hangar to hold monthly meetings. Instead, they seemed to be a bunch of aviation nomads. We know that members often met in the basement of a bank in Milwaukie, then for a long time, they found a home at a hangar at Aurora State Airport. Sometimes they would congregate at a hangar at Lenhardt’s Airport, and for many years they met at the PGE office building at the intersection of Scholls-Ferry Road and Murray Blvd.
In the ’60s and ’70s (we are unclear on the actual dates), the chapter held an annual fly-in at Lenhardt’s, located south of Aurora. Below you can see the approach to 02 on Lenhardt’s airstrip about that time.
Approach to Lenhardt
The Chapter was formally made a non-profit 501c(3) in 1997.
In the following pictures: The first shows planes at an early Lenhardt fly-in. Below this, the RV-3 on the left belongs to Bob Larsell. He is still a chapter member and still lists this RV-3 as one of two that he owns and flies. The guy he is talking to is Carl Battjes, still a member and a former chapter president. The one on the right shows Jerry VanGrunsven winding up an RV-3, concentrating furiously on something important.
To the right, Jerry Springer is standing alongside his Minicoup, and below that Norm Durrell and Dick VanGrunsven man the registration table at a fly-in, taking names and counting the money. Both are still members and former presidents of the chapter.
When anyone talks of the early days, the name Holly Fletcher always comes up. He was a member of great enthusiasm who lived at Dietz Airpark.
