Hi Reader,

Hello and welcome back. It's been a big month for paperwork that actually matters, the kind that changes what you can fly, not just how you file it. This week we're looking at a rule change that snuck past a lot of student pilots without the fanfare it deserved, plus the usual mix of industry news and community reflection. Let's get into it.

For twenty years, "light sport aircraft" meant one thing: small, slow, and simple.

That definition just changed. On July 24, 2026, Phase II of the FAA's MOSAIC rule took effect, and the old 1,320-pound weight limit for light sport aircraft is gone. In its place is a performance-based standard: up to 3,000 pounds maximum takeoff weight, a stall speed no higher than 54 knots, and cruise speeds up to 250 knots.

Read that again. A light sport aircraft can now cruise at 250 knots. That's turboprop territory. Here's the part most people miss. This was never really about weight. The FAA spent years trying to regulate light sport aircraft by how heavy they are, which turned out to be a clumsy proxy for what actually matters: how fast an aircraft flies and how forgiving it is to fly.

Phase II fixes that mismatch by asking the right question directly. For student pilots, this is bigger than it sounds. The old assumption, that a sport pilot certificate meant a slower, simpler flying life than a private pilot certificate, no longer holds.

Manufacturers are already responding. Cosmic Aerospace, a startup, has unveiled the Cosmic One, a four-seat electric aircraft the company says is designed specifically to take advantage of the new rules, with a market launch it's targeting roughly three years out.

If you're weighing which certificate path to pursue, it's worth pausing on this.

The gap between "sport pilot" and "private pilot" just narrowed considerably, and the aircraft available to you under a sport pilot certificate are about to look very different from what your instructor trained on.

SUN COUNTRY AND ITS INSTRUCTORS ARE IN COURT

Sun Country Airlines and the Air Line Pilots Association are trading lawsuits over pay for the airline's instructor pilots.

An independent arbitration board ruled in December 2025 that Sun Country had improperly withheld contractually required premium pay from instructors and ordered back pay. Sun Country sued in March 2026 to void the award, and ALPA has countersued to enforce it.

ALPA has pointed out the irony directly: the airline blames pilot shortages for recent route cuts while fighting a payout to the very pilots who train new recruits.

OSHKOSH SETS A NEW RECORD EAA

AirVenture Oshkosh 2026 drew an estimated 734,000 attendees over its seven-day run in late July, organizers reported, breaking the previous year's record of roughly 704,000.

Visitors came from 98 countries, and the show hosted more than 10,000 aircraft, including a first-ever appearance from the Royal Air Force Aerobatic Team.

REGIONAL CARRIERS ARE FEELING THE SQUEEZE

Several regional airlines have spent the summer running below full pilot staffing, with some operators trimming schedules or parking aircraft because there aren't enough qualified crews to fly them.

It's a reminder that the "pilot shortage" story in 2026 isn't one crisis so much as a set of mismatches, between where pilots live and where they're needed, and between mainline and regional carriers competing for the same pool.

A NEW ELECTRIC AIRCRAFT AIMS AT THE MOSAIC MARKET

Startup Cosmic Aerospace has introduced the Cosmic One, a four-seat electric aircraft the company says is built to take advantage of the FAA's newly expanded light sport category. It's an early sign of how quickly manufacturers are moving to design around the new rules covered in this week's main story. ---

FROM THE COMMUNITY

If you're partway through training and feeling behind, you're not. There's no clock on this. Some of you are flying twice a week, some once a month between shifts and family life, and both of you will get there.

The certificate doesn't know how long it took you. It just knows you didn't quit.

Keep showing up, even when the weather, the money, or the confidence isn't cooperating. That's the whole job right now.

That's this week's edition. Come share your questions, your solo stories, or your MOSAIC opinions in the Student Pilot Community Facebook group, we read every post.

See you next week.
