HARDWARE & RIVET GUIDES - Standard Hardware Decoder: Input standard AN part numbers to instantly break down size, length, thread pitch, and alloy specifications. - Hardware Dimensional Reference: Direct dimensional charts and head markings for aircraft bolts, nuts, and washers. - Rivet Specifications: Look up head markings, material codes, shear strengths, and installation rules for structural rivets. - Drill Bit Gauge Chart: Searchable lookup mapping gauge sizes (#80 to 1") to decimal equivalents. 4. SYSTEM FLOWS & PLUMBING - Fluid Line Color Codes: Identify hazard zones and system functions using official aircraft line tape symbols. - AN Fittings Guide: Match coupling nuts, sleeves, and unions based on material and color identifiers. - Corrosion Guide: High-utility classifications of surface, pitting, and galvanic corrosion. - Safety Wire Reference: Single-wire and double-twist wrap directions, count rules, and lockwire guidelines. - Electrical Tools: Ohm's law calculator and AWG wire size ampacity safety limits. COMPLIANCE & DISCLAIMER This application is designed as a pocket reference tool for educational and general workshop assistance. All calculations must be verified against current and effective aircraft-specific maintenance manuals (AMM) or structural repair manuals (SRM) before performing aircraft maintenance tasks. This application is intended for training and reference purposes only. It does not replace, supersede, or augment official aircraft manuals, airline standard operating procedures, or operator policies. Always refer to current and effective manufacturer documentation (AMM/FIM/MEL) for operational maintenance tasks.
