DJMS-12-JPT-R-0165/0166 – RESPONSES TO QUESTIONS

A. The following responses are provided to questions submitted by industry:

QUESTION #1: RFI/SSN - The notice mentions landing gear at “half-life (5,000 cycles remaining).” Are we correct in assuming this refers to the engines, and landing gear will require a minimum of 5 years remaining life?

RESPONSE: The Statement of Work, Section III, Paragraph B., Item 13(b) requires that all landing gear be at “mid-life.” “Mid-life” for the purposes of this requirement is defined in the Statement of Work, Section III, Paragraph B., Item 13. As an example; a 737-400 aircraft under an MSG-3 maintenance program, mid-life landing gear is considered as landing gear with a minimum of five (5) years or 10,500 cycles remaining life. The Statement of Work, Section III, Paragraph B., Item 13(a) will be amended to read: “Engines offered must have a minimum of 5,000 cycles remaining prior to any scheduled shop visit (scheduled off-wing maintenance). Any recurring inspections must be identified. At time of delivery, engines must be enrolled in a “Power-by-the-Hour” maintenance program.”

QUESTION #2: Draft SOW (Page 3, Section III, B13) - If the aircraft requirement for “39,000 TCSN” were expanded to 42,000 TCSN, there would be a significantly larger sample of available aircraft without a substantial decrease in expected service life. Would USMS consider increasing the allowable TCSN number?

RESPONSE: The Statement of Work, Section III., Paragraph B., Item 11., will be amended to read; ”Aircraft must not have accumulated more than 42,000 total cycles since new (TCSN).”

QUESTION #3(A): RFI/SSN; Draft SOW (Page 3, Section III, B13) - We understand the definition of Mid-Life as it applies to Landing Gear, but are unfamiliar with the term as it applies to:

(a) “all engine life limited components at mid-Life, with Engines on a current and maintained power by the hour maintenance program.” Will you further specify what your hour limitations for each life-limited engine component are?

RESPONSE: See response to Question #1.

QUESTION #3(B): RFI/SSN; Draft SOW (Page 3, Section III, B13) - We understand the definition of Mid-Life as it applies to Landing Gear, but are unfamiliar with the term as it applies to:

(b) Thrust Reversers (TR) and APUs—our experience is that these components are “on-condition” replacements, rather than life limited. Would you provide additional direction?

RESPONSE: The Statement of Work, Section III., Paragraph B., Item 13(c)., will be amended to read; ” Reserved.” The previously identified requirement for the thrust reversers to be mid-life will be deleted. The Statement of Work, Section III., Paragraph B., Item 13(d) will be amended to read; ”Life limited components of the auxiliary power unit (APU), to include, but not limited to, the turbine disc must be at mid-life. At time of delivery, APUs must be enrolled in a “Power-by-the-Hour” maintenance program.”

QUESTION #4: Draft SOW (Page 4, Section III, C 7) - Are we correct in assuming the “ CFM56-3C1 engines without de-rate” phrase, means you want engines rated at a minimum of 23,500#?

RESPONSE: Yes, you are correct.

QUESTION #5 - Draft SOW (Page 10, Section IV, G) - Are we correct in assuming this paragraph’s MSG-3 compliance requirements are applicable at time of delivery of the aircraft?

RESPONSE: Yes, you are correct.

QUESTION #6 - RFI/SSN; Draft SOW (Page 20, Section X, Deliverables) - The RFI/SSN “Aircraft Requirements” requires a “…fresh heavy check (D Check or equivalent) and no calendar maintenance or inspection events due the first 12 months;” and the Draft SOW “Deliverables” tables indicates the aircraft will be delivered “4-weeks after contract award.” This presents a timing challenge, as a 737 D-check can take up to 8 weeks.

Would USMS consider amending the delivery requirement to 10-weeks after contract award?

RESPONSE: Yes, JPATS will amend the delivery requirement to 10-weeks after contract award.
