Joby Aviation (JOBY) traded higher in the latest session as market attention returned to the company’s certification progress, highlighted by Joby beginning flight testing of its first FAA-conforming aircraft aimed at Type Inspection Authorization (TIA) work. That step is viewed as a gating milestone because it connects a conforming design, approved test plans, and production capability—elements needed before FAA test pilots can eventually conduct ‘for-credit’ certification sorties.

Joby disclosed in March that it had started flying its first FAA-conforming aircraft at its Marina, California test site, positioning the program for the TIA campaign that precedes type certification. In late February, the company also told shareholders its first FAA-conforming aircraft for TIA was “set to fly shortly,” and that aircraft required for TIA were in production—language that reinforced expectations for a higher-tempo certification push through 2026.

A separate, near-term overhang has been insider-trading headlines, including an early-April sale by Joby’s chief product officer after option exercises. Today’s bounce suggests the market is treating these sales as limited in scale versus the bigger driver—whether Joby can keep advancing through FAA testing stages without timeline slippage.

The next key signal is confirmation that FAA-controlled ‘for-credit’ TIA flight testing has begun, not just company-led flights of the conforming aircraft. Investors will also watch for updates on the pace of conforming-aircraft production supporting TIA, and any changes to the company’s 2026 operational targets as certification test points accumulate.
