The question posed—how many hours a low-time pilot needs before approaching a Part 135 Lear 35 medevac operator about a first officer position—touches on one of the most persistent friction points in professional pilot career progression: the gap between FAA regulatory minimums and what insurance underwriters and chief pilots actually require to put someone in the right seat of a turbojet air ambulance. A pilot at 260 hours working toward a commercial multi-engine certificate is still well short of the experience threshold most Part 135 operators need to satisfy their aviation insurance carriers, even for an SIC seat that doesn't require an ATP. FAA regulations under 135.243 allow SIC operation with a commercial certificate and instrument rating in many turbojet operations, but real-world hiring for Lear 35 medevac flying is driven almost entirely by underwriting requirements, which commonly call for 500-1,200 total hours, some multi-engine time, and often a certain amount of turbine or complex aircraft experience before an insurer will bind coverage on a new hire, regardless of what the regulation technically permits.
For working pilots and Part 135 operators, this scenario illustrates why the medevac and air ambulance segment occupies a unique niche in the charter and on-demand air taxi world. These operations run older, well-proven airframes like the Lear 35A on demanding schedules—short notice, night flying, unimproved or minimally-equipped destination airports, and time-critical missions carrying patients and medical crews. Because of that risk profile, chief pilots and directors of operations in this sector tend to be conservative about who they put in the right seat, even in an era of persistent pilot shortages that have pushed hiring minimums down across regional and fractional operators. A personal introduction through a family connection can open a door for an interview, but it does not substitute for building the flight time, multi-engine PIC experience, and instrument proficiency that will make an insurance underwriter comfortable, and most owner-operators know this well enough to be candid with a young pilot about what the real bar is versus what the FAA technically allows.
The more strategic path for a pilot in this position is to use the relationship for mentorship and information now, while deliberately building the flight time and ratings that make the eventual application competitive. Finishing the CMEL, accumulating multi-engine PIC time, pursuing a multi-engine instructor rating to build hours efficiently, and ideally getting some turbine or complex aircraft exposure through flight instruction, banner towing, skydiving operations, or similar time-building routes will matter far more than hours alone. Many Part 135 medevac and charter operators also value candidates who have some exposure to night flying, actual instrument conditions, and unfamiliar-airport operations, since those are the day-to-day realities of medevac flying. Asking the operator directly what their insurance minimums are, and what a realistic hiring timeline looks like, is far more useful than guessing—chief pilots in this space are typically happy to lay out a concrete roadmap for a motivated low-time pilot they already know through a personal referral.
This scenario also reflects a broader trend reshaping pilot career pathways industry-wide. As regional airlines and fractional operators have lowered effective hiring minimums to cope with attrition toward the majors, charter and medevac operators flying legacy jets like the Lear 35 have in some cases become relatively more selective, precisely because they can't compete on pay or lifestyle with airline seats and instead lean on experience and reliability to manage risk in a demanding mission profile. For low-time pilots with strong personal connections into this world, the smart play is patience paired with deliberate hour- and skill-building rather than a premature ask, since a poorly timed application can waste a valuable relationship that could otherwise yield a well-supported entry into turbine Part 135 flying once the numbers and experience actually line up.
