Page Aerospace C734-01-030 Obsolete or Backordered? Certified Replacement Available and Traceable

Introduction

When a critical aviation component like the Page Aerospace C734-01-030 shows as obsolete or on extended backorder, it creates immediate operational risk—particularly in Aircraft on Ground (AOG) situations. According to Boeing estimates, AOG events cost operators between $10,000 and $150,000 per hour depending on aircraft type and route. For MRO teams and flight departments managing legacy aircraft, a single unavailable battery component can ground an entire aircraft, triggering cascading costs across crew scheduling, passenger accommodations, and revenue losses.

FAA-PMA approved replacements with full traceability documentation provide a legally compliant path forward—keeping aircraft flying without waiting on OEM supply chains that may never recover.

TLDR:

• The C734-01-030 is a Page Aerospace battery pack for Dassault Falcon aircraft emergency power systems
• OEM supply chain disruptions for legacy components are pushing MRO teams toward certified second-source alternatives
• FAA-PMA replacements are federally approved under 14 CFR Part 21 and legally equivalent to OEM parts
• Proper documentation (FAA Form 8130-3) protects operators from liability and audit failures
• Ni-Cad Systems offers 24/7 AOG support with rental batteries available at +1 510 501-9391

What Is the Page Aerospace C734-01-030?

Component Function and Aircraft Application

The Page Aerospace C734-01-030 is a battery pack designed for the Next Higher Assembly (NHA) D734-02-001, designated as a "Box - Power Supply Assy." This component supplies backup electrical power within the aircraft's emergency power system, keeping critical safety systems online when primary power fails or during emergency lighting operations.

The C734-01-030 is specifically approved for installation on multiple Dassault Aviation aircraft models:

• Dassault Falcon 50
• Dassault Falcon 900
• Dassault Falcon 900EX
• Dassault Falcon 2000
• Dassault Falcon 2000EX

Operational Criticality

This battery pack operates within the aircraft's emergency power supply system, ensuring continued operation of critical safety systems during electrical failures. When this component becomes unavailable or unserviceable, the consequences are immediate:

• Aircraft cannot legally dispatch without functioning emergency power systems
• Airworthiness certification is directly affected until a serviceable unit is installed
• Fleet operators face grounded aircraft until a compliant replacement is sourced

OEM Context and Procurement Challenges

Page Aerospace Inc., originally based in Hollywood, Florida, manufactured this component as part of their emergency power supply product line. The C734-01-030 is called out by this exact part number in Aircraft Maintenance Manuals (AMMs) and Illustrated Parts Catalogs (IPCs) for Dassault aircraft. Substitution is a compliance question, not just a sourcing one — any replacement must carry proper FAA approval documentation.

For maintenance professionals, that means you can't swap in an alternative without verifying it matches the aircraft's type certificate requirements.

Why Is the C734-01-030 Obsolete or Backordered?

Parts like the C734-01-030 don't disappear from catalogs overnight. Several structural forces push legacy aviation components into NLA or extended backorder status — and once they do, the clock starts ticking on grounded aircraft.

What's Driving Aviation Parts Obsolescence

According to a joint 2025 report by IATA and Oliver Wyman, parts shortages, MRO delays, and AOG events are projected to cost the airline industry more than $11 billion in 2025.

Common drivers of obsolescence include:

• OEMs discontinue low-volume legacy parts when production is no longer economical
• Parts shortages push MRO turnaround times up by 15-20% across the industry
• Acquisitions and ownership changes routinely eliminate inherited product lines
• Components for older aircraft models lose supplier support as fleets retire

Operational Impact of NLA Status

When critical components like the C734-01-030 reach No Longer Available (NLA) status, the operational consequences extend far beyond simple inconvenience:

Direct Costs:

• Aircraft ground time ranging from days to weeks
• AOG events costing $10,000-$150,000 per hour
• Unplanned lease costs for replacement aircraft
• Crew duty time violations requiring substitute crews

Indirect Costs:

• Increased spares inventory requirements (airlines have increased inventory by 8% on average)
• Inventory holding costs adding $1.1-$1.3 billion across global fleets
• Schedule disruptions creating network-wide delays

These compounding costs make finding a certified alternative — not just waiting on backorder — a business-critical decision.

The FAA-PMA Solution

The FAA established the Parts Manufacturer Approval (PMA) pathway specifically for this scenario. When OEM supply is constrained or cut off entirely, PMA approval gives operators a legal, airworthy second-source option — one that meets the same safety and performance standards, with full traceability documentation.

What Does FAA-PMA Certified Mean for a Replacement Part?

Understanding FAA-PMA Approval

FAA-PMA (Parts Manufacturer Approval) is a combined design and production approval granted by the FAA under 14 CFR Part 21, Subpart K. This authorization allows manufacturers to produce replacement aviation parts that meet or exceed OEM specifications. PMA parts are not "aftermarket" in the unregulated sense — they are federally regulated and subject to rigorous FAA oversight.

Two Approval Pathways

The FAA recognizes two methods for demonstrating airworthiness:

1. Identicality Method

• The PMA holder proves their design is identical to the original type-certificated article
• Can be achieved with or without licensing agreements from the OEM
• Requires comprehensive design data comparison

2. Test and Computation Method

• The manufacturer independently validates engineering data through testing
• Common for battery and power supply components
• Requires comprehensive safety assessment and performance validation

For battery pack components like the C734-01-030, the test-and-computation method typically applies, requiring extensive electrical performance testing, thermal cycling validation, and safety analysis.

Legal Equivalence Under Federal Regulations

FAA-PMA approved parts can legally replace OEM parts on type-certificated aircraft. Under 14 CFR Part 21, Subpart K, PMA parts are federally approved alternatives that A&P mechanics can install without violating airworthiness requirements.

The regulatory framework requires PMA holders to:

• Establish quality systems meeting § 21.137 requirements
• Maintain the same manufacturing oversight level as OEM Production Certificates
• Provide traceability documentation for every unit produced
• Submit to ongoing FAA surveillance and audits

Verified PMA Replacement for C734-01-030

A direct FAA-approved PMA replacement is available for the C734-01-030:

The Aero Design AD-C734-01-030 is approved via the rigorous Test and Computations pathway, making it a legally equivalent and airworthy substitute for the OEM part.

Addressing Operator Concerns

Some operators worry that PMA parts void warranties or create liability. Properly documented PMA parts carry their own FAA-backed approval. The actual liability risk lies in using unapproved or undocumented parts — not in using certified PMA components.

Ni-Cad Systems holds 30+ FAA-PMA approvals across aircraft battery and power supply components, with over 50 years in the aviation battery industry and a Part 145 FAA-approved repair facility. This positions them as a credible, regulated source for C734-01-030 replacements. For specific documentation on available replacements, contact their technical team at +1 510 785-9391.

Traceability and Documentation: What You Should Expect

Defining "Traceable" in Aviation Procurement

In aviation parts procurement, "traceable" means documented chain-of-custody records that verify origin, manufacturing approval, and conformity. The four core documents you should expect with any compliant replacement part:

Why Traceability Matters Beyond Compliance

Complete documentation protects each party who touches the part before it reaches the aircraft:

• Shields operators from FAA audit failures and preserves aircraft resale value
• Demonstrates MRO compliance with repair station requirements under Part 145
• Protects A&P mechanics' certificates in post-incident investigations
• Provides liability defense at every level when incident reports are filed

The FAA has pursued certificate action against mechanics who installed parts without proper 8130-3 documentation — even when those parts appeared functional. Documentation gaps don't just create compliance risk; they transfer liability to whoever signed off on the installation.

Red Flags for Receiving Inspectors

FAA Advisory Circular 20-62E outlines critical warning signs:

Documentation Red Flags:

• Missing FAA Form 8130-3 tags
• No reference to PMA approval data
• Generic Certificates of Conformance from non-certificated distributors
• "As-removed" parts without inspection records

Physical Red Flags:

• Missing "FAA-PMA" markings (required under 14 CFR 45.15)
• Altered or unusual surfaces
• Evidence of prior usage without proper overhaul documentation
• New paint over old finishes
• Absence of required plating

When sourcing a C734-01-030 replacement, request the 8130-3, PMA supplement number, and batch records before purchase — not after. A supplier who can't produce those documents at the quote stage is unlikely to produce them at delivery.
