[Tab 1: Compliance Standard] Commercial Fleet Maintenance Policy (2026 Audit Standards): -… — GMAT

[Tab 1: Compliance Standard]
Commercial Fleet Maintenance Policy (2026 Audit Standards):
- Category A Aircraft (Long-Haul): Heavy maintenance (C-Check) is required whenever an aircraft reaches 24 elapsed months since its last C-Check OR accumulates 6,000 total flight hours, whichever occurs first. The standard base inspection fee is $120,000. - Category B Aircraft (Regional): Heavy maintenance (C-Check) is required whenever an aircraft reaches 18 elapsed months since its last C-Check OR accumulates 4,000 total flight hours, whichever occurs first. The standard base inspection fee is$ 80,000.
- Overhaul Surcharge (Rule 4.2): If an aircraft has logged more than 75% of its total flight hours in high-corrosion maritime environments, a 15% surcharge is added to its base inspection fee. However, this surcharge is waived if the aircraft completed an anti-corrosion hull upgrade within the preceding 12 months.

[Tab 2: Fleet Utilization Log]
| Aircraft ID | Category | Months Since Last C-Check | Total Flight Hours | Maritime Flight Hours (%) | Last Anti-Corrosion Upgrade |
| N-101 | Category A | 20 | 5,800 | 80% | 14 months ago |
| N-202 | Category A | 22 | 6,100 | 70% | 8 months ago |
| N-303 | Category B | 16 | 4,200 | 82% | 10 months ago |
| N-404 | Category B | 19 | 3,900 | 60% | Never |

Based on the policy guidelines and utilization data provided across both tabs, what is the total dollar amount in base inspection fees and applicable surcharges that the airline must allocate immediately for aircraft currently requiring a mandatory C-Check?

A
$200,000
$280,000Answer
C
$292,000
D
$322,000
E
$418,000

Answer

$280,000

Evaluating both tabs demonstrates that aircraft N-202, N-303, and N-404 exceed their operational threshold criteria (N-202 and N-303 on flight hours, N-404 on elapsed months). Aircraft N-202 and N-404 do not exceed the 75% maritime threshold, incurring base fees of

120,000 and

80,000 respectively. Aircraft N-303 exceeds the 75% maritime threshold, but because its anti-corrosion upgrade was completed 10 months ago (within the 12-month window), the 15% surcharge is waived, resulting in a base fee of

80,000. Summing these values gives

280,000.

Step-by-Step Solution

Evaluate mandatory C-Check threshold compliance for each aircraft combining rules from Tab 1 and data from Tab 2.

N-101 (Cat A): 20 months (< 24) and 5,800 hours (< 6,000) -> No check required.
N-202 (Cat A): 22 months (< 24) but 6,100 hours (>= 6,000) -> MANDATORY CHECK REQUIRED.
N-303 (Cat B): 16 months (< 18) but 4,200 hours (>= 4,000) -> MANDATORY CHECK REQUIRED.
N-404 (Cat B): 19 months (>= 18) and 3,900 hours (< 4,000) -> MANDATORY CHECK REQUIRED.

An aircraft requires an immediate C-Check if it meets or exceeds EITHER the monthly limit OR the flight hour limit for its specific category.

Calculate inspection fees and evaluate Rule 4.2 surcharge conditions for required aircraft.

N-202: Base

120,000. Maritime is 70% (<= 75%), so no surcharge applies. Total =

120,000.
N-303: Base

80,000. Maritime is 82% (> 75%), but anti-corrosion upgrade was 10 months ago (<= 12 months), waiving the surcharge. Total =

80,000.
N-404: Base

80,000. Maritime is 60% (<= 75%), so no surcharge applies. Total =

80,000.

Tab 1 specifies that the 15% surcharge applies only when maritime hours exceed 75%, and is explicitly waived if an upgrade occurred within the last 12 months.

Sum the fee allocations for all non-compliant aircraft.

120,000 +

80,000 +

80,000 =

280,000.

Combining the calculated costs yields the total immediate budget allocation required.
