Montgomery County Airpark

Montgomery County Airpark Since 1960, Montgomery County Airpark (KGAI) has been where the DC metro area takes flight. montgomerycountyairpark.com | (301) 978-7009

One of the region's busiest general aviation airports and a vital part of the Gaithersburg community.

If you saw a large military aircraft at Montgomery County Airpark this morning, there is no cause for concern. The Airpark occasionally supports military and medical transport missions, and this morning's was one of them, coordinated with local emergency services. It's a role we're glad to play. Our thanks to the crews and first responders involved.

Some of the most important flights at Montgomery County Airpark are also the ones you will never hear about.

Several times a year, life-saving organ transport flights launch from KGAI, moving donated organs to transplant centers across the region under tight, time-critical deadlines. Donated organs have only hours of viability, and general aviation aircraft are often the fastest way to get them where they need to go. No commercial schedule. No layovers. Just wheels up, mission complete.

This is part of what the Airpark has quietly made possible. Not every flight out of KGAI is a lesson or a business trip. Some are someone's second chance at life. 🫶

🛩️ Future pilots in the making at Goshen Elementary!

Airpark Manager Justin Bollum recently joined Chelsea Dorman of the Maryland Aviation Administration (MAA) at Goshen Elementary School's "Propelling Our World" STEM event, and what a day it was.

Together, Justin and Chelsea connected with hundreds of students and families, handing out Pilot's Guides to the Montgomery County Airpark and Maryland aeronautical charts. Both are licensed pilots, and they used aircraft models and hands-on demonstrations to teach kids the basics of how planes actually fly and all the different parts of an airplane.

The best part? Students who answered aviation questions correctly took home a balsa wood plane courtesy of the MAA. (We're pretty sure a few flight paths were tested in the school parking lot afterward.)

Events like this are exactly why the Airpark exists in the community to inspire the next generation of pilots, engineers, and aviation professionals right here in Montgomery County. Huge thanks to Goshen Elementary for the invitation and to the MAA for being a great partner.

Aviation Fuel and the Transition to Unleaded: What KGAI Neighbors Should Know

At the March town hall, several community members asked about aviation gasoline (avgas) and lead emissions. Here's what everyone should know about where the industry stands and where it's heading.

The Current Situation - Most small aircraft engines still use 100LL (low-lead) aviation gasoline, which contains tetraethyl lead. This fuel has been the industry standard for decades because it prevents engine knock in high-performance aircraft engines. The EPA estimates that general aviation accounts for about 70% of atmospheric lead emissions in the United States.

Why This Matters Lead exposure poses health risks. While aviation lead emissions are a small percentage of total lead exposure sources, the EPA and the aviation industry recognize the need to eliminate them entirely. Airborne lead emissions have been reduced by 99% since the 1980’s by the phase out of leaded car gas.

The Path Forward - The FAA launched the EAGLE (Eliminate Aviation Gasoline Lead Emissions) initiative with a goal of transitioning the fleet to unleaded fuel by 2030. Several unleaded aviation fuels are in testing and certification phases. Some aircraft can already use unleaded alternatives, and that number grows as more fuels gain approval.

At KGAI As unleaded aviation fuels become commercially available and certified for the aircraft based here, Montgomery County Airpark will support the transition. This is an industry-wide change happening at airports across the country, driven by federal policy and aircraft manufacturer approvals.

The Bigger Picture - Environmental monitoring for aviation facilities falls under EPA and state environmental agency oversight. The Maryland Department of the Environment discontinued statewide ambient lead monitoring in 2017 with EPA approval because levels were consistently below detection limits.

One of the most common questions we hear is some version of: who is actually responsible for what at the Montgomery County Airpark?

It is a fair question. The answer is more layered than it might appear, and we want to be clear about it.

The Montgomery County Revenue Authority (MCRA) owns the land and is responsible for the runways, taxiways, and airfield safety. MCRA is also the FAA grant sponsor, which means federal infrastructure investment - like the North End hangar project currently in development - flows through MCRA.

The day-to-day operation of the terminal, hangars, tie-downs, fueling, and line management is handled by DC Metro Aviation LLC, a private company that operates those parts of the Airpark under a long-term master lease agreement.

The FAA licenses and oversees pilots, flight schools and aircraft operations. The Maryland Aviation Administration licenses the airport and conducts annual inspections.

Understanding who does what matters - especially when you have a question or a concern. If it is a noise or safety issues, start at https://www.montgomerycountyairpark.com If it is a question about hangar or terminal operations, that falls under DC Metro. If it is about airfield infrastructure, that is MCRA.
