Maintenance, inspection, or replacement as it pertains to this document, is used to

describe any procedure that requires the shell body to be opened. Opening the shell body

allows maintenance, inspection, and replacement of critical internal components. For this

manual, maintenance does not include the pre­flight, flight or post­flight procedures and visual

inspections outlined in Exhibit A and B.

Sydor Aerial Photography has the expertise and experience in maintaining and replacing

the internal components of the DJI Phantom 2 Vision. However in anticipation of further UAS

regulations it has determined that safe­flight operations can and should require unbiased,

independent maintenance, inspection, or replacement by an equally qualified UAS entity.

Authorized Dji representatives / service technicians are the most qualified individuals to

conduct annual inspections of DJI UAS.

As current UAS maintenance regulations have yet to be finalized, Sydor Aerial

Photography proposes annual, and as needed, maintenance to ensure safe­flight

operations.

1) Sydor Aerial Photography will submit its DJI Phantom 2 Vision to an authorized DJI

representative,

A) On an annual basis.

B) Or if during pre­flight, flight or post flight the PIC or VO determines that continued safe

flight operations requires maintenance.

2) The internal components listed for inspection, function, maintenance,

or replacement include,

A) DJI Phantom 2 Vision Main Controller

B) DJI Phantom 2 Vision Central Circuit Board (Central Circuit Board is viewed atop the

Main Controller for location reference.)

C) DJI Phantom 2 Vision Internal Power Connector.
D) DJI Phantom 2 Vision CW (Clockwise) Engine.

E) DJI Phantom 2 Vision CCW (Counter Clockwise) Engine.

F) DJI Phantom 2 Vision ESC (Electronic Speed Controller)

G) DJI Phantom 2 Vision GPS Module.

H) DJI Phantom 2 Vision Receiver Module

3) Before the DJI Phantom 2 Vision is placed back in “operational status” following an

annual or as needed inspection, function, maintenance, or replacement of internal

components. The entire UAS (UA, Remote Controller, Wifi Extender, Ground Control

System) will be subject to two separate functional flight tests.

A) Since most failures of repaired or replaced electronic components occur within the

first 2 hours of service the UAS will be started. During this functional test the UA will

not have the CW or CCW propellers attached. The UA will function for 2 hours at

70% power. The purpose of the first functional test is to verify that the following

components, and their respective electronic connections, are operating properly

1) Main Controller

2) Central Circuit Board

3) Internal Power Connector

4) CW and CCW Engines

5) ESC (Electronic Speed Controller)

6) Receiver Module

Upon satisfactory completion of the first functional flight test, by the PIC, the UAS

will begin the second functional flight test.

B) In a secure location, 500ft from people or structures, the UAS will be started

and the UA will complete the basic, skilled, advanced, and emergency procedures

outlined in Exhibit D. The purpose of the second functional test is to verify that the

following components, and their respective electronic components, are operating

properly

1) Compass

2) GPS Module

4) Upon successful completion, determined by the PIC, of both functional flight tests, the UAS

will be placed back in "operational status".
