What the numbers show

N8123V is costing more to maintain than it did a year ago.

N8123V$5,133 est more maintenance this year

Maintenance came to about $33 per hour flown this year against $26 the year before, about $5,133 more over this year's hours.

Ideas schools in this spot often explore

  • Whether the repairs share a cause (one system, one part) that a single fix would address.
  • Which maintenance items drove the rise, and whether they're one-offs or likely to recur.
  • How the aircraft's maintenance per hour compares with the rest of the fleet.

Ideas, not recommendations. Your situation may differ.

The cash flow forecast has months where more goes out than comes in, January 2027 most of all.

N4521K, N744PS, N8123V−$82,230 short est in January 2027

In the forecast, revenue there is expected at about 61% of an average month, and N744PS's engine overhaul ($84,000) falls in it, leaving about $82,230 more going out than coming in.

Ideas schools in this spot often explore

  • When the large cost has to be paid: a deposit, payment terms, or financing that spreads it over several months.
  • What brings in revenue in the slow months: ground school, simulator time, or block-time packages sold ahead of winter.
  • Timing maintenance that isn't due yet into the stronger months before or after it.

Ideas, not recommendations. Your situation may differ.

N8123V$2,100 est Scheduled value of cancelled hours

11% of bookings were cancelled or no-shows, 12.0 scheduled hours worth about $2,100 at the usual rate; most fell on Saturdays.

Ideas schools in this spot often explore

  • Whether the day most cancellations fall on has something in common: weather patterns, instructor rosters, or a recurring group of students.
  • 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.

Ideas schools in this spot often explore

  • Where fuel is purchased and at what price: contract pricing, self-serve against full-serve, and fuel-card fees.
  • Leaning and run-up procedures in the syllabus, and whether they're followed consistently.
  • Whether the hourly rate or a fuel surcharge moves with fuel prices.

Ideas, not recommendations. Your situation may differ.

Owner payouts booked for N8123V don't match the leaseback terms.

N8123V$219 est booked vs owed

The payments in QuickBooks are about $219 less than what the terms in fleet setup give in this period.

Ideas schools in this spot often explore

  • Whether the leaseback agreement's payout terms still fit what the aircraft earns and costs to run.
  • Which months' owner payouts differ from the agreement, and whether a payment was missed, doubled, or paid on old terms.
  • What the aircraft would need to earn per hour, after the owner's share, to cover its own costs.

Ideas, not recommendations. Your situation may differ.

N8123V's next inspection falls in the same two weeks as other aircraft's.

N8123V

N8123V flew 32% 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.
