EZ Flap is the big performance & safety upgrade for manual flap aircraft. Now you can sit upright while using the flaps, and stay focused on takeoff/landing, terrain, traffic, and instruments. No more bending over, no more lost visibility. EZ Flap finally allows the safe use of advanced & expert STOL flap techniques for MAX performance!

Regardless of “inertia reels”, fixed harness, or no shoulder harness at all… you are guaranteed to have faster, better, and more precise control of your flaps.

Mounts to OEM flap handle with no disassembly in 30 minutes. Proudly made in the USA. FAA approved on 95% of all US manual flap aircraft.


Before installation, please verify that your EZ Flap unit is the correct unit for your aircraft. EZ Flap is produced in two different styles, which cover nearly all US built manual flap aircraft. However, the two styles are not interchangeable. Installing the incorrect version will not work, is not approved, and may cause unsafe interference with other aircraft components. Before proceeding, please verify that you have purchased the correct EZ Flap unit for your aircraft! The original style EZ Flap unit has a data tag specifying part number EZ-16, and a three digit serial number hand engraved on the very bottom of the unit next to the threaded clamp bolt holes such as 001, 016, 027, 152, etc.

Original model fits:

  • Cessna 170, 172, 175, 180, 182 and 185
  • Piper PA-28, PA-32, PA-34, PA-44 (“Cherokee” family)
  • Beechcraft 19 /23 /24 (“Musketeer” family)

EZ Flap “Style 18” units have a data tag specifying part number EZ-21, and a four digit serial number beginning with “18-“ hand engraved on the very bottom of the unit next to the threaded clamp bolt holes such as 18-06, 18-30, 18-54, etc.

Style 18 model fits:

  • Piper PA-18, PA-19, PA-20, PA-22 (“Super Cub”, “Pacer”, “Tri-Pacer” family)
  • Stinson 108 family
  • Maule Aircraft family

If your aircraft parts supplier has accidentally shipped the incorrect EZ Flap unit for your aircraft, feel free to contact EZ Flap directly and we will exchange the product for the correct unit at no charge. Please DO NOT attempt to install the wrong unit on your aircraft - there is a difference, it is not safe or legal, and you will not experience all the performance or safety benefit available for your aircraft.


  • More Performance - More Safety - More Control - More Visibility
  • No Distractions During Takeoff & Landing
  • Sit Upright - eyes out of the cockpit - face out of the panel
  • No more bending forward and down for the flap handle
  • FAA Approved on all 4 Seat: Cessna - Piper - Maule - Stinson - Beechcraft With Manual Flaps

Greatest invention since sliced bread! I have owned my 1958 Cessna 172 since 1985. Best $500 I have spent On this wonderful machine. Something has happened to my body over the years. Gradually, almost insidiously, It became more difficult to reach for the flap handle without me realizing it. Consequently, I gradually shunned using flaps and just slipped to landings on all but the shortest fields. Old age has a way of sneaking up on a person. My son is now the same age I was when I purchased the airplane. When he asked me why I wasted $500, I simply told him he will understand when he reaches my age. I have now rediscovered the use of flaps without the pain to apply flaps and much more quickly to retracting them , enabling shorter stopping distances. A great product for those pilots that are somewhat physically challenged. Perhaps, the best way to put it is either get the EZ Flap extension or an airplane with electric flaps! Either way, your body will thank you in return. Lloyd Mason

Excellent idea and implementation. Very much an ergonomic improvement! Less leaning forward to actuate flaps especially that first click, and more sitting straight up with shoulder straps tighter. Construction good and installation straightforward. Wish I had thought of this STC!

This EZE Flap / flap extender is a great addition to my 108-3 Stinson...it allows me to have much better control of my flap settings and without having to bend over. For me its most beneficial on landing when control is most critical, I can get the flaps out much faster now and never lose sight of the runway. Great addition to my aircraft. Bob Crow N743C

Installed in my 175 in less than 10 minutes. Now, I can wear the shoulder restrains. The flap handle is close enough that I dont bend down and loose sight of the final. Worth every dime.

Completely agree with Mathew L, not having inertia belts meant having the seat belts very loose, and reaching down your head was below the panel. This spoilt your perspective of the approach. worth every cent.

Big safety improvement in our plane's operation. After a year's use I can say that this EZ Flap Handle Extension works great in our 1957 Cessna 172 (tailwheel conversion), with fixed shoulder straps. Previously, with shoulder harness engaged, the flap handle was not reachable without releasing strap tension. With the handle extension, 10 and 20 degrees of flaps come right to hand. Additional flap deployment of 30 and 40 degrees is accomplished by grasping the flap handle's original grip. No more messing with the shoulder harness when I want flaps now. Solid construction, effortless use.

so far it seems great. I have only used it on one flight so this is not much of a review. Your price was competitive and it arrived quickly.

Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base.

Q: Regarding the EZ Flap: How do you push the button to release the flaps with this device installed?

The short answer is that there is a trigger on the EZ Flap which the pilot pulls with their finger, right underneath the grip, that "pushes the button" on the aircraft flap system. Note, the "Trigger" is a remote release using a "Bowden Cable". mechanism.

Q: After installation of the EZ flap extension handle, do I require sign-off by AME (Canadian Aircraft)?

Yes, the EZ Flap will require the same AME signoff as for any approved STC modification. The product is fully STC-PMA approved in the US, and this approval is accepted without difficulty in Canada for a US-built aircraft (Cessna, Piper, Maule , Stinson, Beech). Because the EZ Flap is very simple and risk-free to install, the overwhelming majority of government inspectors (IA in the US, AME in Canada) will allow the owner to do most or all of the installation work and simply inspect it and sign it off afterwards. The entire installation manual is available for free download in the 'Documents' tab on this web page.

Q: Does the purchase price include the STC or is there an added fee for the STC?

Yes, the STC paperwork is in the box.

Q: How much does this system weigh?

Approx 16 oz.
