What the numbers show

N744PS's engine is getting close to overhaul.

N744PS$84,000 est Overhaul cost

With 100.0 tach hours left at the pace it usually flies through the seasons, it's projected for May 2027, at about $84,000 (your setting).

Ideas schools in this spot often explore

  • Overhaul quotes and shop slots, since lead times can be long.
  • How the overhaul will be paid for (reserve, financing or cash) and when the money is needed.
  • Overhaul, exchange or a factory engine: what each costs, and how long the aircraft would be down.

Ideas, not recommendations. Your situation may differ.

N744PS's engine is projected to reach its 2,000-hour TBO about May 2027 (100.0 tach hours remaining at about 16.4 a month, through the seasons).

N744PS is booked for much longer than it flies.

N744PS$82,397 est booked, not flown

It flew about 58% of the time booked, leaving time worth about $82,397 that no one else could book.

Ideas schools in this spot often explore

  • Whether the booking length for these lessons includes briefing time that could be booked separately, so the aircraft is free sooner.
  • How long bookings are blocked for: whether the default block fits the lesson, or leaves time nobody uses.
  • Whether bookings start on time, and what happens to the time when a lesson ends early.

Ideas, not recommendations. Your situation may differ.

Show the numbers

N744PS flew 289.7 of its 498.3 booked hours (58%) in this period; the fleet flew 70% of its booked time. The 208.6 booked hours not flown are worth about $82,397 at its revenue per hour.

Cancellations are costing N744PS real flying time.

N744PS$15,800 est Scheduled value of cancelled hours

11% of bookings were cancelled or no-shows, 40.0 scheduled hours worth about $15,800 at the usual rate; one instructor was on most of them.

Ideas schools in this spot often explore

  • What's different about the bookings of the instructor on most of them: students, times, or workload.
  • Whether the time of day most cancellations fall in has something in common: early starts, end-of-day slots, or weather.
  • How the cancellation and no-show policy is set: notice period, fees, and whether it's applied consistently.

Ideas, not recommendations. Your situation may differ.

N744PS$20,601 est cost rise not in the rate

Since its rate last changed, its cost per hour has gone from about $255 to $306, about $20,601 over the hours flown since.

Ideas schools in this spot often explore

  • Whether fuel prices or fuel burn per hour account for the rise.
  • When the lease terms changed, and whether the rate was reviewed then.
  • When the hourly rate was last reviewed against its cost per hour.

Ideas, not recommendations. Your situation may differ.

N744PS's next inspection falls in the same two weeks as other aircraft's.

N744PS

N744PS flew 19% of the fleet's hours, and the others are due within days of it, so they could all be down at once.

Ideas schools in this spot often explore

  • Bringing one inspection forward a few days so the aircraft aren't down at the same time.
  • Whether the shop can take two aircraft in the same week, and how long each would take.
  • Which bookings fall in those weeks and could move to other aircraft.

Ideas, not recommendations. Your situation may differ.
