MassDOT sent an email to airport managers reporting that as of May 5th, aircraft registrations for 2022 are down by half. They asked that managers forward the message to all aircraft owners and remind them that registration is required.

This is the first year MassDOT has converted from a paper / snail mail system to a new online system from SalesForce. My personal experience was that the system was very confusing and difficult to use. If you need to register your aircraft, you can access the MassDOT registration system here: https://www.mass.gov/how-to/how-to-register-an-aircraft

Note that when I completed my registration, they had not carried over previous registrations and I had to register a new aircraft. For first access, click the "Not a member?" link to create a new account on the MassDOT site.
