Overview

Mission

To foster & preserve the history of grassroots aviation in the united states.

Operating model

Revenue model
Donor-supported. 89% of the money available for current operations came from contributions and gifts.
Distribution model
Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.

The verdict

SUPPORTED - A large share of total spending goes to programs and the filed numbers largely add up. A relatively small share of available resources goes toward mission work and reported officer compensation is a large share of total spending, which may reflect staffing concentration.
